摘要
室温条件下在水溶液中合成了粒度分布均匀、分散性好的CdS纳米粒子.研究了pH值、反应时间等条件因素对其吸收光谱和荧光光谱特性的影响,并探讨了CdS纳米粒子-酚藏花红体系的光谱特性、可能的作用机理和应用前景.
CdS nanoparticles were directly synthesized in aqueous solution at room temperature. Absorption and fluorescence spectra of CdS nanoparticles at different pH values and reaction time were investigated. At the same time, the spectroscopic characteristics and application values of the CdS-phenosafranine system were also discussed.
