【摘要】 以CaCl2、K2B4O7和Nd2O3为原料,采用易于工业化、无污染的水溶液法反应合成碱-碱土金属硼酸盐K2O·CaO·4B2O3·12H2O:Nd3+晶体,利用X射线衍射、红外光谱、扫描电镜、荧光分光度计等现代分析测试手段,对所合成晶体进行了分析和表征。结果表明,所制备的K2O·CaO·4B2O3·12H2O:Nd3+晶型发育良好、形貌规整。基质本身具有上转换发光特性,K2O·CaO·4B2O3·12H2O:Nd3+的发光强度较基质弱。当激发源为828 nm时,材料呈橙红色光。更多还原

【Abstract】 Alkali-alkaline earth borate K2O·CaO·4B2O3·12H2O:Nd3+ was investigated by easy industrialization and pollution-free water solution method.K2B4O7,CaCl2,Nd2O3 were used as starting materials.The production was characterized by chemical analysis,FT-IR spectra,X-ray powder diffraction and SEM,fluorescence spectrum,etc.The results show that K2O·CaO·4B2O3·12H2O:Nd3+ have fine shape and tidy surface.The matrix material had upconversion luminescence property,and the intensity of K2O·CaO·4B2O3·12H2O:Nd3+ was weaker than matrix,both of them appeared orange emission under 828 nm excitation.更多还原
