Structural and Optical Properties of High Entropy (La,Lu,Y,Gd,Ce)AlO₃ Perovskite Thin Films.

ABSTRACT: Mixtures of Ce-doped rare-earth aluminum perovskites are drawing a significant amount of attention as potential scintillating devices. However, the synthesis of complex perovskite systems leads to many challenges. Designing the A-site cations with an equiatomic ratio allows for the stabilization of a single-crystal phase driven by an entropic regime. This work describes the synthesis of a highly epitaxial thin film of configurationally disordered rare-earth aluminum perovskite oxide (La_0.2 Lu_0.2 Y_0.2 Gd_0.2 Ce_0.2 )AlO₃ and characterizes the structural and optical properties. The thin films exhibit three equivalent epitaxial domains having an orthorhombic structure resulting from monoclinic distortion of the perovskite cubic c
