Perovskite metal oxides offer a wide range of functionalities owing to their rich compositional diversity. Experimental results have shown that much-enhanced physical properties could be achieved by forming multicomponent or high-entropy perovskite oxides. In this talk, we discuss our efforts in the design and synthesis of compositionally disordered epitaxial perovskite metal oxide films with multiple A-site cations. Using rare-earth aluminum perovskite oxide with an equiatomic ratio (La<sub>0.2</sub>Lu<sub>0.2</sub>Y<sub>0.2</sub>Gd<sub>0.2</sub>Ce<sub>0.2</sub>)AlO<sub>3</sub> as the model system, we show that a high entropy oxide system with equiatomic A-site cations allows for the achievement of desired optical luminescence observed in mixtures and/or doping of RE aluminates while maintaining a highly crystalline single-phase. The high crystallinity of these materials paves the way for exciting new research of high precision scintillating applications.
