| 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. |
