氧化锌量子点和碳量子点及其复合物的制备与发光性能的研究OA北大核心CSCDCSTPCD
Preparation and Optical Properties of Zinc Oxide,Carbon and Their Quantum Dot Mixture
采用溶胶凝胶方法和水热法制备了水溶性荧光氧化锌量子点(ZnO-QDs)和碳量子点(C-QDs),其量子效率分别达到38%和61%.基于所合成的ZnO-QDs和C-QDs制备了氧化锌和碳量子点复合物(ZnO/C-QDs),并分别对其发光特性进行了研究.透射电镜(TEM)图像表明,所合成的ZnO-QDs和碳量子点尺寸分布在3~6 nm之间,分散均匀.光致发光光谱表明,ZnO-QDs和碳量子点的发光峰中心分别位于540 nm和450 nm,两者发光峰的…查看全部>>
Water-soluble fluorescence zinc oxide quantum dots ( ZnO-QDs ) and carbon quantum dots ( C-QDs) were prepared by sol-gel and hydrothermal method, and their quantum yields were 38% and 61%, respectively. ZnO and carbon quantum dots mixtures ( ZnO/C-QDs) were prepared based on the as-prepared ZnO-QDs and C-QDs, and their optical properties were investigated, re-spectively. The transmission electron microscopy ( TEM) images indicate that the size of ZnO-QDs and…查看全部>>
