摘要/Abstract

摘要： A series of Eu³⁺ doped of M'type of yttrium orthotantalate Y_1-x Eu_x TaO₄( x =0—0.30) was sythesized. The influence of activator concentration on luminescence properties was studied in detail. The strong evidence from excitation spectra, emission spectra and diffusive reflection spectra of this system shows that there is energy transfer from TaO₄^3- to Eu³⁺ via the charge transfer and spectral overlap.
