Thông tin chi tiết

Tóm tắt :

Dy3+-doped glasses with various compositions (30+x)B2O3+ (60-x)TeO2 + 9Na2O + 1Dy2O3 (x = 10 and 20) were prepared by a melt–quenching technique. The specifically structural properties of boro-tellurite glasses with the high borate content (> 30 mol%) was reflected in the unusually large values of the Judd-Ofelt parameters Ω2 and Ω6 . The CIE chromaticity color coordinates were calculated from the luminescence spectra of Dy3+ ions of the glasses with the different compositions and all of them were located in the white light zone of the color coordination diagram.
