Fluorescence Effect of SrAl2O4∶Eu and Diffuse Reflectivity of SrAl2O4∶Eu Based Ceramics

SrAl 2O 4∶Eu was adopted as main phase to prepare the ceramic pumping cavity material with ultraviolet(UV) converting function in order to match with laser absorption spectra. The relationship between SrAl 2O 4∶Eu powder processing and fluorescence effect was studied. The glass material with lower refractive index was added to the SrAl 2O 4∶Eu based ceramics. The diffusive reflectivity and the influence of fluorescence effect on reflection spectra of the ceramics were investigated. Some experimental results can be used for evaluating technical feasibility of the SrAl 2O 4∶Eu based ceramics used for laser reflectors.
