Abstract
We report on a feasible method to synthesize luminescence nanocrystals in porous glass in this paper. Well dispersed YVO 4:Eu nanocrystals were proved being grown in nanoporous glass by XRD, micro-Raman spectra and HRTEM equipped with EDS. The YVO 4:Eu 3+ nanocrystal grown in porous glass herein shows very different luminescence properties compared with single Eu-doped sample. By this method, intense red emission from high silica glass due to energy transfers VO 4 3− → Eu 3+ was obtained. The results show that the reduction from Eu 3+ to Eu 2+ in porous glass impregnated with Eu 3+ ions was avoided effectively.
