Emerging blue‐UV luminescence in cerium doped YAG nanocrystals
Source abstract
Abstract
Time‐resolved luminescence properties of Ce3+ doped Y3Al5O12 (YAG) nanocrystals have been studied by means of vacuum‐ultraviolet excitation spectroscopy. It was discovered that additionally to the regular Ce3+ yellow‐green emission which is well‐known luminescence in YAG, new emission covering a broad spectral range from 2.7 eV to 3.5 eV was revealed in the luminescence spectra for all YAG:Ce nanocrystals studied. This blue‐UV emission has fast decay time about 7 ns as well as intensive well‐resolved excitation band peaking at 5.9 eV and, in contrast to green Ce3+ emission, practically is not excited at higher energies. The origin of the blue‐UV emission is tentatively suggested and discussed. (© 2016 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim)
