Abstract
The photoluminescence properties of BaGdB9O16: Eu3+, Nd3+ were investigated under ultraviolet excitation. For the samples BaGdB9O16: xEu3+, yNd3+, the emission spectra include the visible and near infrared region, which correspond to the emission spectra of Eu3+ and Nd3+. Moreover, based on the luminescence spectra and decay lifetimes of BaGdB9O16: 0.01Eu3+, xNd3+, the effective energy transfer was demonstrated from Eu3+ to Nd3+. The energy transfer efficiency was calculated with the measured decay lifetimes of Eu3+. The possible energy transfer mechanism was proposed to rationalize the experimental results.
