Abstract:

A novel alkali-alkaline earth borate K2O•CaO•4B2O3•12H2O：Sm3+ has been synthesized by facile industrialization and pollution-free water solution method .The samples were characterized by chemical analysis, FT-IR spectra, X-ray powder diffraction and SEM, fluorescence spectrum. It is found the product owns rhombic group space, about 3mm long. Under 828 nm excitation, the fluorescence spectrum is indicated that the host material K2O•CaO•4B2O3•12H2O has properties of infrared-visible up-conversion，and it appears orange. Adding Sm 3+ makes emission spectrum stronger.
