CdTe@SiO₂ Particles Prepared via Reverse Microemulsion Method: A Linear Connection between Shell Thickness and Tetraethylorthosilicate

Abstract:

Fluorescent core/shell CdTe@SiO₂ particles were prepared via reverse microemulsion method. When all the other parameters were kept constant, a simple linear relation was deduced to describe the connection between SiO₂ shell thickness and volume of tetraethyl orthosilicate(TEOS). The results indicated that linearity and morphology of CdTe@SiO₂ were better when the volume of TEOS ranged from 5μl to 200μl. Nevertheless, further decreasing the volume of TEOS to 2 μl led to a poor spherical regularity and if the volume of TEOS was larger than 200μl, size changes of CdTe@SiO₂ were no more clear because of restrained size of water pool
