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.
