Study on Energy Splitting of γ-LiAlO₂:Fe³⁺ Ceramic as a Functional Inorganic Material Sintered by Microwave Based on Material Applications

Abstract

The γ-LiAlO2: Fe3+ ceramics were successfully fabricated by using multi-mode cavity microwave furnace, which can be used as an optical functional material. The sample’s photo luminescence spectrum was measured at room temperature. There are six bands in the range of 12000-25000 cm-1. Using the crystal-field theory and introducing the average covalent factor model, we calculated the energy splittings of Fe3+ ions in γ-LiAlO2. These bands were firstly explained and assigned and calculation results are in good agreement with the optical experiment data. All results can be used for the production of optical devices.
