Photoluminescence and transmittance of Sm3+-doped Sr3Al2O6 glasses synthesized by an aerodynamic levitation furnace

Ying Li,Jia Liu,Xiwei Qi,Aihua Mao,YongHong Ma

A series of transparent (3- x ) Sr 3 Al 2 O 6 - x Sm 2 O 3 amorphous spheres were well fabricated using an aerodynamic levitation furnace with an x -value ranging from 0 to 0.065. In the visible light region, the maximum transmittance was approximately 80% for x  = 0, 82% for x  = 0.025 and 85% for x  = 0.055. The excitation peak located at 405 nm was the strongest. The maximum intensity of the photoluminescence spectra appeared at 0.045. The chromatic coordinates of the CIE were all in the orange region.
