Description

The photoluminescence and excitation spectra of Pr3+ activated strontium aluminate (SAO), which are Hot Isostatic Pressing (HIP) processed and normally sintered, has been investigated at the room temperature (300 K). The luminescence excited by Xe 172 nm consists of optical transitions emanating from the 4f5d and the 1S0 states of Pr3+. As for the HIP-processed samples, the emission from 1S0 and 3P0 were observed. On the other hand, as for the samples which were made in a tubular furnace, no emission from 1S0was observed and UV emission of 250-350nm (4f15d1->4f2) was observed. The results of energy-dispersive X-ray spectroscopy (EDS) analysis show that SrAl14O25 is made by HIP-processed, and that SrAl2O4 was made with a tubular furnace. These results show that quantum-cutting phosphors can be obtained by Pr3+ activated SrAl14O25.
