Effect of Alkali Metal Doping on Luminescence Properties of CaMoO4:Sm3+Phosphors Prepared by High Temperature Solid-Phase Method
In the field of inorganic luminescent materials,it is worth noting that calcium tungstate,an excellent material with stable chemistry and physical properties.In this study,a series of white phosphors doped with Sm3+with a single matrix CaMoO4 could be prepared using the high-temperature solid-phase method.Its phase structure is tested using XRD,and the luminescence performance can be tested by excitation and emission spectroscopy.The final study found that when the concentration of Sm3+doped in calcium molybdate(CaMoO4)was 0.020,the phosphor had the strongest luminescence performance,and when the alkali metal was further doped as a charge compensator,CaMoO4:0.020Sm3+had the best luminous intensity,and the K+-doped phosphor sample had the largest luminous intensity,indicating that this phosphor had unrevealed development prospects in terms of LED illumination.
