Blue pigments and blue glazes play crucial roles in our daily life. Ongoing research into blue pigments aims at environmentally friendly compositions with a lower cost. In this work, Co-doped BaAl2Si2O8 pigments were synthesized by a solid-state method. The blue color of the pigments is due to the 4A2(4F) → 4T1(4P) transitions allowed by doped Co2+ in the tetrahedral coordination of the structure. The pigments exhibit excellent stability under both acidic and alkaline conditions. When combined with transparent glazes, BaAl2–xCoxSi2O8 demonstrates satisfied compatibility, resulting in blue glazes with a significant reduction in Co content compared with existing formulations. Furthermore, BaAl2–xCoxSi2O8 blue glazes possess a simple production route, commendable color performance, and cost-effectiveness.

The severe urban heat island effect emphasizes the heightened importance of reducing building energy consumption. Cool pigments with higher near-infrared reflectivity contribute to the overall coating performance of the building. In this work, a novel intense blue pigment with superior infrared reflectance based on Ni-doped Zn2SiO4 was successfully synthesized via the simple solid-state method. The crystal structure, oxidation states, and optical properties are analyzed. The oxidation state of Ni was confirmed to be +2 using magnetic analysis and XPS. The intense blue color exhibited by the solid solution is due to the 3T1(3F) → 3T1(3P) transition of Ni2+ at the tetrahedral sites. UV–vis–NIR spectra demonstrate that this pigment exhibits superior near-infrared reflectance compared to cobalt blue in the range of 900–1700 nm, indicating its potential application in the realm of building energy conservation.

Mn-doped Ba 7 Al 2- x Mn x O 10+ y (0 ≤ x ≤ 0.7) samples with intense blue colors are successfully prepared by solid state reactions. With the increase of Mn content, the colors of compounds are tuned from cyan to ocean blue. FT-IR absorption spectrum and 27 Al NMR spectrum indicate that the structure contains a dominating portion of Al–O tetrahedral sites while a small number of Al–O octahedral sites may also exist. The oxidation state of Mn is proved to be +5. Based on all the analysis, the intense blue shades of the samples are proposed as the d-d transition of Mn 5+ ions in [AlO 4 ] tetrahedral sites.

In this work, the Li/Zn-doped near-infrared reflective inorganic blue pigment YIn0.9–xMn0.1MxO3−δ (M = Li/Zn, x = 0–0.4) was synthesized by the high-temperature solid-state reaction method. The phase structures, morphologies, color properties and optical properties of synthetic pigments were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), CIE1976 color space system, UV–vis-NIR spectrophotometer, and other instruments. All the doped samples have a hexagonal structure with space group P63cm (185). Compared with YIn0.9Mn0.1O3 (b* = −45.91), Li/Zn doped pigments have richer blue hues (b* is ranged from −29.59 to −55.14), which can meet the needs of public’s demands for blue hues. The NIR solar reflectance (R*) of all the samples are above 70%, and the highest R* with different doping concentrations can reach 86% (M = Li, x = 0.2), which is about 16% higher than YIn0.9Mn0.1O3. YIn0.9–xMn0.1MxO3−δ (M = Zn/Li, x = 0–0.4) are indicated to possess higher near-infrared solar reflectivity than other blue compounds, including commercial products. The surface temperature difference between the Li-doped (x = 0.2)/Zn-doped (x = 0.1) paints and commercial ultramarine paint can reach about 20 and 10 °C, respectively. The above properties ensure the potential applications of environmentally friendly YIn0.9–xMn0.1MxO3−δ pigments with a rich blue-hue in the field of energy-saving materials.

The YIn 1-x Mn x O 3 ( 0.1 ≤ x ≤ 0.5 ) blue pigment samples are successfully prepared through a sol-gel process followed by microwave assisted sintering process. All the samples are shown single phases in the X-ray diffraction results. In the morphology study from scanning electronic microscope, the samples are composed of loosely connected small particles. The oxidation state of Mn is confirmed to be 3 + from the results of X-ray photonelectronic scan. The optical properties are characterized by UV–Visible spectrum and UV-visible-NIR spectrum. The samples exhibit intense blue color and they show small absorption in infrared region.

To alleviate the urban heat island effect, reduce building energy consumption and improve the living environment for residents, the development of highly reflective pigments and coatings is of great significance for sustainable development. In this study, Mg 2.4- x Cr x TiO 4.4+δ (0.1 ≤ x ≤ 0.3) and Mg 2.4- x Co x TiO 4.4 (0.1 ≤ x ≤ 0.4) pigments with intense green/sky blue colors were successfully synthesized through solid state method. The crystal structure, color development mechanism and optical properties of as-synthesized samples are analyzed. The as-prepared pigments demonstrate excellent NIR reflectance with the highest solar reflectance up to 83%. Furthermore, the color coatings with high NIR solar reflectance were successfully prepared by mixing the pigments with acrylic resin. A solar reflectance of 69.81% is achieved among the green/blue coatings. The thermal shielding effect of the coatings in practical applications was tested through chamber simulation experiments. The test temperature of the prepared coating was 8.8 ℃ lower than that of the blank stainless steel plate after radiating with a 250 W infrared lamp for 30 minutes, which proved its good heat insulation performance. Through pickling and alkali washing experiments, the color coordinates of the coatings are very stable, indicating the excellent acid-base resistance in the practical applications.
