Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A polyacrylamide gel route is used to synthesize the alumina-based light-emitting material M: -Al2O (M=C, Fe, Co, Ni, Mn, Ti). Sintering temperature, pH value, organic additive, chelating agent, C and metal salt can significantly effects the formation of rhombohedral -Al2O phase. The structure analysis shows that the carbon, Ti, Co, Ni doped Al2O powders obvious suppress the formation of -Al2O , in contrast, the Fe, Mn doped Al2O3 can accelerate the formation of -Al2O . The carbon and metal salt introduction to the Al2O precursor solution obvious influenced the sample morphology, band-gap, color and photoluminescence properties. The results show that the carbon and metal salt introduced to Al2O precursor solution reduces the band-gap values and enhances the photoluminescence properties of M: -Al2O powders. The photoluminescence mechanisms of M: -Al2O powders have been discussed on the basis of the experimental results. The M: -Al2O composites making them promising candidates as efficient light-emitting materials, pigments, photocatalysts and radiation detection including space dosimetry, environmental dosimetry, medical dosimetry and personal dosimetry. 152 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -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. 700 pp. Englisch.…
