)以等浓度0.005mol/L配制成两种反应溶液
通过化学溶液法在玻璃衬底上生长出ZnO六角型亚微米棒(长5~8μm
直径300~700nm)。测量了样品的XRD和扫描电镜像。经XRD分析
所得样品均为纤锌矿的ZnO六角型晶体。扫描电镜(SEM)像表明
生长时间为3h或5h时
样品为细长条的棒状结构
长径比超过10:1;生长48h后的ZnO亚微米棒的一端被腐蚀成一定深度的ZnO亚微米管。用负离子配位四面体生长模型分析了ZnO亚微米棒的生长机理。ZnO亚微米棒退火前后的光致发光谱表明
退火处理后的发射谱中的紫外峰消失
而红色发光峰红移并且增强(峰值由630nm左右移到710nm)
同时它的激发光谱中的室温激子激发峰也增强。
