Its typical morphology and chemical composition are confirmed by scanning electron microscopy (SEM) and energy-dispersive spectrometry (EDS). The valence states of all elements and the internal/external vibrational modes of NaCoP 3 O 9 compound are measured by X-ray photoelectron and vibrational spectrum, where a typical feature of the (PO 3 ) − polyanion group is observed. Meanwhile, the electrochemical properties of NaCo(PO 3 ) 3 cathode for sodium-ion batteries are also elevated and an initial discharge capacity of 33.8 mAh/g can be obtained at 0.05 C within 1.5–4.2 V. After 20 cycles, a discharge capacity of 26.7 mAh/g can be obtained and a well-kept oxidation–reduction plateau is still observed for NaCo(PO 3 ) 3 cathode, indicating the good reversibility of this metaphosphate electrode.

The effect of Na3(PO3)3 on the growth of KDP crystal (101) faces was studied by the Michelson interference technique and atomic force microscopy. The experimental results show that the growth rates were near zero at low supersaturation when Na3(PO3)3 was doped into solution, i.e., there was a supersaturation interval similar to the “growth dead zone”. The growth rates began to increase rapidly as the supersaturation crossed the “growth dead zone” and continued to increase. The “growth dead zone” increased as the doping concentration was increased. In addition, the anisotropy of growth hillocks decreased and the competition of growth hillocks became more intense when the doping concentration of Na3(PO3)3 was gradually increased in solution at confirmed supersaturation. The calculated surface free energies of three adjacent planes show that they increased with the increase of doping concentration and always αI, αII > αIII.

KNi(PO 3 ) 3 was successfully synthesized by solid-state method and the magnetic properties were characterized. The crystal structure of KNi(PO 3 ) 3 belongs to trigonal crystal system with space group R 3, where Ni 2+ ions form the distorted honeycomb-lattice within the ab-plane stacking in the “ABAB” type fashion along the c -axis. Magnetization measurements reveal the presence of antiferromagnetic (AFM) interaction with Curie Weiss (CW) temperature θ CW = − 12.905 K but without long-range magnetic order down to 2 K. Notably, the CW fitted effective moment µ eff = 3.35µ B and saturated magnetization M S = 2 μ B /Ni 2+ at 2 K support KNi(PO 3 ) 3 as an S = 1 spin system. Intriguingly, the zero-field specific heat exhibits a broad peak maximized at ~ 2.5 K indicating the onset of short-range spin correlation between Ni 2+ ions, while the integrated magnetic entropy ( S mag ) is close to the expected Rln3 for S = 1 system, indicative of large spin fluctuation below 2 K driven by spin frustration.

In this study, NaMg 1- x Mn x (PO 3 ) 3 (0.00 ≤ x ≤ 0.0625) ceramics with low dielectric constant were prepared via the solid-state reaction method. The effects of Mn 2+ substitution on the microstructure and dielectric properties (at microwave and terahertz frequencies) of the NaMg(PO 3 ) 3 ceramics were studied by means of the Rietveld refinement, morphology, and ionic polarizability analysis. It is obtained that the NaMg 0.0975 Mn 0.025 (PO 3 ) 3 ceramic sintered at 880 °C for 4 h exhibited optimal dielectric properties at microwave frequencies, where ε r = 4.585, Q × f = 48,313 GHz (@17.228 GHz), and τ f = −40.83 ppm/°C. The Q × f and τ f values were changed by 74.2 % and 27.8 %, as compared to the values of 27,728 GHz and −56.52 ppm/°C for the pure NaMg(PO 3 ) 3 ceramic, respectively. For terahertz frequencies (0.2–1.0 THz), the ε r values were decreased to 3.79–3.98, and the tan δ values were between 0.0203 and 0.1152. All the experimental results indicate that this system exhibits great potentials both at microwave and terahertz frequencies.

Ni-rich layered LiNi 0.80 Co 0.15 Al 0.05 O 2 (NCA) cathode materials have attracted extensive attention in power lithium ion batteries on account of their high specific capacities and low voltage delay. However, they still suffer from inferior cycling stability, especially operating at a high cutoff voltage. In this paper, a surface modification strategy was proposed by utilizing Al(PO 3 ) 3 as a coating material to enhance the cycling performance of NCA in 2.7–4.6 V (vs. Li/Li + ). The surface modification effects of Al 3+ lattice doping and Al(PO 3 ) 3 coating were verified to be well achieved. In particular, besides the functions in stabilizing surface crystal structure of the NCA and isolating the erosion from electrolyte, the Al(PO 3 ) 3 coating could eliminate the residual lithium on the NCA surface to in-situ generate the Li 3 PO 3 which was conductive to the rate performance. Accordingly, the Al(PO 3 ) 3 -modified NCA cathode delivered excellent cycling performance, of which the initial discharge capacity was 235.9 mAh . g −1 at high cutoff voltage of 4.6 V, with a capacity retention of 71.6% after 100 cycles at 1 C. This work demonstrates the feasibility of surface modification on NCA via the phosphate coating with multiple functions, and provides an efficient approach to improve the cycling stability of Ni-rich layered cathode materials at higher cutoff voltage.

Fluoro-sulfo-phosphate (FPS) glass is of current interest as potential material for laser application due to its good glass-forming ability, thermal, and chemical stability as well as the complicated local environment for incorporated species. Herein, the physical and luminescent properties of Er 3+ and Yb 3+ /Er 3+ -doped FPS glasses vs S/F ratio are investigated comprehensively. The low melting temperature (750°C) leads to fewer ingredients evaporation and easier operation. The sulfate addition depolymerizes the structure of FPS glasses, leading to either monotonic or nonmonotonic variations of physical properties, while no deterioration in thermal and limited one in chemical stability is caused. The addition of sulfate also modifies the local structure around optical active species and thus, leading to higher emission cross section (1.52 × 10 −20 cm 2 ), effective linewidth (68.4 nm), figure of merit (5.61 × 10 −23 s cm 2 ), gain bandwidth (102.44 × 10 −27 cm 3 ), and energy-transfer microparameters (51.87 × 10 −39 cm 6 /s), implying high possibility to serve as 1.5 μm laser application.

For Mn-activated phosphors, the luminescent performance is strongly dependent on the oxidation state of Mn. In this paper, a series of red phosphors NaMg(PO3)3:xMn2+ (NMP:xMn2+) were synthesized by high temperature solid-state reaction in the open atmosphere. The single oxidation state of Mn2+ was confirmed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and photoluminescence spectroscopy (PL). We suspected that a self-reduction process occurred to prevent the oxidation of Mn2+. The doped Mn2+ ions occupy the strong crystal field environment of the Mg site (octahedral point), forming a red luminescence center with a peak position centered at 630 nm and a full width at half maximum (FWHM) of 80 nm. The thermal stability and quenching luminescence are explained by the temperature dependence of the PL spectrum. The results show that the NaMg(PO3)3:Mn2+ red phosphor has potential applications in LED backlight display areas.

For phosphate nonlinear optical (NLO) materials, how to improve their small birefringence is confronted with a great contradiction of their weak optical anisotropy of tetrahedral PO4 groups. Herein, by introducing La3+ with a closed-shell structure and Cd2+ with a d10 electronic configuration, two NLO materials with a large birefringence, namely, La(PO3)3 (0.040@1064 nm) and β-Cd(PO3)2 (0.059@1064 nm), have been synthesized by a high-temperature solution method. In particular, for β-Cd(PO3)2, it possesses the largest birefringence among the known deep-ultraviolet (DUV) phosphates to date, which is attributed to cooperative effects of strong covalence of Cd–O groups and P–O pseudolayers similar to those of a plane. Meanwhile, β-Cd(PO3)2 exhibits the shortest cutoff edge (<190 nm) among the reported Cd-based inorganic compounds and realizes a balance between DUV transparence and a large birefringence. This insight provides a new opportunity to design high-performance NLO materials using metal phosphates.

Short-wave infrared (SWIR) light sources, as crucial components of SWIR imaging and spectroscopy technologies, have garnered significant attention recently. The rapid development of portable electronic devices has created a demand for compact and efficient SWIR emitters, and phosphor-converted SWIR LEDs represent the optimal technological solution to meet this requirement. Here, a Cr(PO3)3:Yb3+ phosphor with highly efficient and pure SWIR luminescence under 450 nm blue LED excitation is reported. Upon doping with Yb3+ in the Cr(PO3)3 matrix, the resulting material is capable of effectively converting blue excitation photons to SWIR luminescence spanning from 900 to 1200 nm, with a dominant emission peak at 1003 nm due to the efficient energy transfer from Cr3+ to Yb3+. Notably, this phosphor demonstrates an ultrahigh internal quantum efficiency (IQE) of 95.7% and a record external quantum efficiency (EQE) of 60.3% upon 450 nm blue light excitation. Moreover, the fabricated SWIR LED prototype device by combining the Cr(PO3)3:Yb3+ phosphor and a commercial 450 nm blue LED chip exhibits SWIR output power of 24.1 mW at 200 mA input current and a photoelectric conversion efficiency of 12.8% at 20 mA. This study not only opens avenues for realizing high-efficiency SWIR luminescence by deliberately controlling energy transfer pathways in Cr-based material systems but also paves the way for the development of high-power SWIR light sources.

Organic phosphorous wastewater is very hard to be purified which need to remove both COD and phosphorous. The treatment process of organic phosphorous wastewater is commonly complicated. In this work, CaO has been used as the catalyst and precipitant for the treatment of organophosphorus wastewater by catalytic ozonation . Compared with CeO 2 , MnO 2 and MgO, CaO shows excellent catalytic performance for the removal of COD. Additionally, the generated PO 3 3− can be removed by Ca 2+ . Ca 2+ can catalyze the reaction between O 3 and H 2 O to generate active oxygen species, such as • OH, - • O 2 , 1 O 2 . Besides, various conditions, namely, amount of catalyst, O 3 flow rate, substrate concentration and pH for the degradation of Tetrakis Hydroxymethyl Phosphonium Sulfate (THPS) wastewater by catalytic ozonation over CaO have been optimized to determine the optimal parameter conditions. Finally, the excess Ca 2+ in the solution can be removed by the addition of CO 2 .
