Calcium acuminate matrix (CaAlBO 4 ) was prepared at temperatures 1160°C by soild state reaction, a spectroscopy analysis of Cr 3 + 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 4A 2 →4T 1 and 4A 2 →4T 2 transition of Cr 3 + ion, and emission spectra with the strongest emission peak 694 nm owing to the 2E 2 →4A 2 transition of Cr 3 + ion. Also, the influences of the concentration of Cr 3 + ion on the luminescent properties in CaAlBO4 compounds were investigated, which the optimal concentration is 0.5mol%.
