新型纳米氧化钨的近红外吸收性能
Tungstate Oxide for Absorbing Near Infrared Light
摘要
Abstract
A nano-powder of tungstate oxide was firstly prepared by a chemical precipitation process, and then the powder was reduced in H2/N2 gases at a high temperature. The phase and chemical composition of tungstate oxide before and after reduction were investigated by X-ray powder diffraction. The morphology of tungstate oxide before and after reduction was observed by scanning electron microscope. The absorption and transmittance spectra of tungstate oxide in a sol state from visible to near infrared wavelength were determined. The results indicated that the tungstate oxide after reduction had a high absorbance in 1 400-1 600 nm and 1 900-2 200 nm wave band for near infrared light and a high transmittance for visible light. It is suggested that the nano-powder of tungstate oxide with the special absorbing characteristics may be promising to be applied in the design for novel solar heat shielding.关键词
