Effects of Heat-Treatment on Photoluminescence Spectra and Photocatalytic Properties of Solution-Combusted ZnO Nanopowders

This paper studied the preparation of TiO2 whisker with melt phase-splitting method, which used tataniferous blast-furnance as the main raw materrial. XRD and SEM were used to research the phase and morphology of the sample, and by the same time, the photocatalytic properties of TiO2 crystal-beards was tested.The result have shown:the size of TiO2 crystal-beards was sub-micron rank, the crystal type wasβ-TiO2 of orthorhombic high-pressure phase. The generation of TiO2 crystal-beards were effected mainly by the content of Na2O and TiO2, and the heat treatment temperature. The sample had certain photocatalytic properties and the highest photocatalytic efficiency was 56%.

AbstractComposites based on polyvinylchloride with incorporated CdSe/ZnS nanoparticles are produced. The optical and electrical properties of the polymer composites containing CdSe/ZnS nanoparticles are studied. The absorption and photoluminescence spectra of the composites are recorded, and their bulk resistivities are measured. The CdSe nanoparticle dimensions are determined. It is established that, upon short-term heat treatment, the photoluminescence intensity increases, whereas upon heating for a long time, the photoluminescence intensity substantially decreases.
