Abstract

Using photoluminescence, photoluminescence excitation, and secondary ion mass spectroscopy (SIMS) investigations we show in this paper that two luminescence objects with different PL excitation spectra exist in PS. Two stages of photoluminescence aging were observed which are connected with desorption and oxidation processes.
