摘　　要：在无机发光材料领域里,值得注意的是具有稳定化学及物理性质的优良材料钼酸钙。本次研究使用高温固相法制备一系列单一基质Ca MoO_(4)掺杂Sm^(3+)的白光荧光粉,并使用XRD测试其物相结构,用激发和发射光谱测试发光性能。最终研究发现钼酸钙(CaMoO_(4))中Sm^(3+)掺杂浓度为0.020时,荧光粉发光性能最强。当进一步掺杂碱金属作电荷补偿剂时,CaMoO_(4):0.020Sm^(3+)的发光强度最优异,其中掺杂K^(+)的荧光粉样品具有最大的发光强度,表明这种荧光粉在发光二极管照明方面具有深远而广阔的发展前景。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 Sm^(3+)with a single matrix CaMoO_(4)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 Sm^(3+)doped in calcium molybdate(CaMoO_(4))was 0.020,the phosphor had the strongest luminescence performance,and when the alkali metal was further doped as a charge compensator,CaMoO_(4):0.020Sm^(3+)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.
