铈铕掺杂氯硅酸镁钙体系的相对光谱功率分布与色坐标定位
Relative Spectral Power Distribution and Emission Color Coordinates of Ce3+ and Eu2+ Doped Calcium Magnesium Chlorosilicate System
摘要
Abstract
A series of Ce3 + and Eu2+ doped Cas Mg( SiO4 )4CI2 powder were synthesized by high-temperature solid-state reaction. The crystal structure was investigated by X-ray jiffraction (XRD) and the fluorescence spectra were also recorded and analyzed. The relative spectral power distribution was obtained by spectral power calibration curve, and the emission color coordinates of samples were calculated and characterized. The XRD spectrum indicate that the phosphor is Ca8Mg( SiO4 )4C12 with face centered cubic lattice. Ce3+ and Eu2+doped Cas Mg( SiO4 )4C12 samples present purplish-blue and green colors under the excitation of ultraviolet radiation, and the corresponding color coordinates are (0. 157 3, 0. 052 8) and (0. 154 0, 0. 466 3),respectively. In Ce3 +/Eu2+ codoped Ca8 Mg ( Si04 ) 4 C12 powder, the introduction of Ce3+ changes the luminescent color obviously, and with the increasing of concentration Ce3+ , the color coordinates shift to the greenish blue color region.关键词
