This book focuses on the photoluminescence and photocatalytic activities of spinel oxides, and studies the effects of different synthesis pathways, morphologies, A-site and B-site ion doping, metal particle modification and heterostructure construction on photoluminescence and photocatalytic activities of aluminate. Due to its high melting point, high thermal and chemical stability, high photocatalytic activity and non-toxicity, spinel aluminate has been widely used in light helmet, infrared window, photocatalyst and light emitting devices. In particular, aluminate has strong radiation resistance and is a potential candidate for the space station’s lighting system. The spinel-type aluminates were confirmed that it can be applied in treating wastewater pollution and photo-degradation of pollutants. Through experiments and theoretical analysis, the internal correlation mechanism between photoluminescence and photocatalysis is revealed. Through the study of various synthesis parameters, doping methods and heterostructure construction methods, it provides technical support for the synthesis of high-performance optical emission devices and photocatalysts with special needs.
