Modern era of double perovskite nano-phosphors: La₂MgTiO₆, Gd₂MgTiO₆ and Y₂MgTiO₆ – a brief review

Abstract

Double perovskites, as a star material, are becoming a significant research domain due to their flexible structure, variable formulae, unique properties and wide applications. Trimming the materials into nano regime and introducing rare-earth integration would improve their properties and broaden their applications. The main purpose of this work lies in the comparison of luminescence properties of double perovskite nanophosphors La2MgTiO6 (LMT), Gd2MgTiO6 (GMT) and Y2MgTiO6 (YMT). A detailed list of numerous excitation and corresponding emission wave lengths are discussed. Various synthesis methods adopted for the fusion of these materials, which are reported till this date, are also considered. This study shall assist the scientific community to identify the suitable host for luminescent applications in the field of lighting, displays, illumination, biological imaging, biological sensing etc.
