| Abstract: | We report on a feasible method to synthesize luminescence nanocrystals in porous glass in this paper. Well dispersed YVO4:Eu nanocrystals were proved being grown in nanoporous glass by XRD, micro-Raman spectra and HRTEM equipped with EDS. The YVO4:Eu3+ 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 VO43− → Eu3+ was obtained. The results show that the reduction from Eu3+ to Eu2+ in porous glass impregnated with Eu3+ ions was avoided effectively. |
