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

摘要：

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 200ul. 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.
