Influence of Growth Conditions on the Elastic Properties of SrLaAlO₄ and SrLaGaO₄ Crystals Studied by Brillouin Scattering Method

Study of the elastic properties of SrLaAlO₄ (SLA) and SrLaGaO₄ (SLG) crystals has been reported. The absorption of the yellow and green SLA and SLG crystals in the visible range was also investigated. The results obtained are discussed in terms of the nature of the oxygen point defects, which might be created in the crystals during the growth process.

Keywords: oxides, oxides point defects, Brillouin scattering
