Eu3+ luminescence in novel garnet-type Li5La3Nb2O12 ceramics
Source abstract
Abstract
Abstract A novel Li 5 La 3 Nb 2 O 12 :Eu 3+ phosphor was synthesized by the solid-state reaction at high temperature. The phase purity of products was checked by XRD. The emission spectrum is independent of the excitation wavelength and the 5 D 0 – 7 F 2 transition is the dominant one. In the excitation spectrum, there are some sharp peaks originating from the f–f transitions of Eu 3+ and a broad band peaking at about 280 nm. The concentration dependence of emission intensity and decay curves of 5 D 0 – 7 F 2 transition were investigated. The temperature dependence of emission intensity and decay curves were also investigated in detail.
