Luminescence properties of Eu3+-doped SiO2–LiYF4 glass–ceramic microrods
Source abstract
Abstract
Abstract Photoluminescence properties of the glass–ceramics microrods containing Eu3+-doped LiYF4 nanocrystals have been studied and characterized. Judd–Ofelt parameters and quantum efficiency has been computed from luminescence spectra and discussed by comparison to the glass ceramic bulk and pellet. The radiative decay rate Arad is higher in the glass ceramic rods (221 s−1) than in the glass ceramic bulk (130 s−1) but the quantum efficiency computed is very low (21%) compared to the glass–ceramic bulk (97%). There are effective non-radiative decay channels that might be related to an influence of the dimensional constraints imposed by the membrane pores during xerogel formation and subsequent glass ceramization.
