摘要

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，两者发光峰的最佳激发波长为370 nm和350 nm。通过调整ZnO-QDs和C-QDs的体积比，所制备的ZnO/C-QDs能够实现荧光光谱的连续可调，并产生了白色荧光。

Abstract

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

respectively. The transmission electron microscopy (TEM) images indicate that the size of ZnO-QDs and C-QDs are around 3-6 nm and disperse uniformly. The photoluminescence (PL) spectra of ZnO-QDs and C-QDs dominate by a broad emission centered at around 540 nm and 450 nm

and their optimal excitation wavelengths are 370 nm and 350 nm. By adjusting the volume ratio between ZnO-QDs and C-QDs

the spectra of as-prepared ZnO/C-QDs show continuously variable properties

and white fluorescence can be observed from the ZnO/C-QDs.
