摘要

本文采用一种简单的紫外辅助法制备了CdS纳米晶体。采用XRD、FTIR、TEM、UV-vis、PL等方法对制备的纳米碳纳米管进行了表征。合成的纳米颗粒呈六方相，平均尺寸约为3.5 nm。当光照时间从3分钟增加到12分钟时，NCs带隙从3.6 eV缩短到3.2 eV。当光照时间从3分钟增加到12分钟时，PL光谱呈现白色发射，PL峰从518 nm附近移到540 nm附近。

UV-Assisted Synthesis of White Emissive CdS Nanocrystals at Room Temperature

In this work CdS nanocrystals (NCs) were synthesized by a simple UV-assisted method. Prepared NCs were characterized by means of XRD, FTIR, TEM, UV-vis, and PL analyses. Synthesized NCs was in hexagonal phase with an average size about 3.5 nm. The NCs bandgap shorten from 3.6 to 3.2 eV only by increasing the illumination from 3 to 12 min. PL spectra showed a white emission and PL peak shifted from near 518 nm to 540 nm by increasing illumination time from 3 to 12 min.
