Abstract

The luminescent properties of different MxIIM 1-xIIAl2S4:Eu and M IIAl2S4:Eu are researched in this paper. A novel assessment method is used to evaluate these materials base on the configuration coordinates model. Vibronic coupling parameters of these phosphor materials can be calculated by the formula. With the calculation of characteristic energy and unitless factors, performances of Mx IIM1-xIIAl2S4:Eu and MIIAl2S4:Eu are evaluated. We then concluded that BaAl2S4:Eu shows highest Φ value comparing with other single or complex thioaluminates. With increasing amounts of Ba and Ca ions in the BaxMg1-xAl2S4:Eu and Ca1-ySryAl2S4:Eu respectively, the complex thioaluminates gives better luminescent performance and a broad tunable emission color can be achieved.
