摘要
用硝酸从钨酸铵水溶液中析出了h-WO3 (P6/mmm, PDF 33-1387)纳米晶，其形貌为厚度~10 nm，直径可达200 nm的纳米片。用DTA和XRD测定证实，h - β相变发生在T= 385℃。记录了沉淀相和煅烧相的红外光谱和拉曼光谱。这些晶体显示出一些特殊的特征，解释为不寻常的微观形态和纳米尺寸范围的几何形状的影响。
Relationship of spectral characteristics and crystal morphology of h-WO3 nanoplates
Nanocrystals of h-WO3 (P6/mmm, PDF 33-1387) with uncommon morphology of nanoplates with ~10 nm thickness and up to 200 nm in diameter have been precipitated with nitric acid from aqua ammonium tungstate solution. The h - β phase transition occurs at T= 385°C as it have been established with DTA and XRD measurements. IR and Raman spectra have been recorded for precipitated and calcined phases. These crystals show some specific features explained as an effect of uncommon micromorphology and nanosize range geometry.
