Abstract

Ca12Al14O32F2 luminescent powdered phosphors doped with rare earth elements Eu3+was successfully synthesized using a wet chemical method to identify the most suitable phosphor based on the measurement of their emission spectra at excitation wavelengths. The XRD pattern of the phosphor was well matched with its standard JCPDS file. SEM images revealed irregular morphology. PL excitation and emission spectra clearly indicated that the phosphor containing the Eu3+ activated Ca12Al14O32F2 phosphors could be efficiently excited at 396 nm and exhibited an emission mainly including two wavelength peaks at 593 nm and 620 nm.
