Abstract
Calcium acuminate matrix (CaAlBO4) was prepared at temperatures 1160°C by soild state reaction, a spectroscopy analysis of Cr3+ doped CaAlBO4 based on excitation spectrum and emission spectra was performed. Broad band excitation spectra are observed with 414 nm and 553 nm. respectively owing to the 4A2→4T1 and 4A2→4T2 transition of Cr3+ ion, and emission spectra with the strongest emission peak 694 nm owing to the 2E2→4A2 transition of Cr3+ ion. Also, the influences of the concentration of Cr3+ ion on the luminescent properties in CaAlBO4 compounds were investigated, which the optimal concentration is 0.5mol%.
