Abstract EN
For this study, we prepared colloidal ZnS quantum dots using 3-mercaptopropyltrimethoxysilane (MPS) as the capping agent.
Colloidal ZnS quantum dots were directly deposited on glass substrates by a spin coating process.
Therefore, self-assembled films made of ZnS quantum dots in a SiO2 network were obtained using only one production step.
The films were heat-treated at 100°, 125°, 150°, 175° and 200°C in an N2 atmosphere.
The results showed that the dimension of quantum dots changed from 2.8 nm to 3.2 nm by heat treatment.
The refractive index, extinction coefficient, thickness, and dielectric coefficient values of the films were calculated.
The present study showed that size and the refractive indices of films can be controlled by the heat treatment.
Therefore, such films can be a good candidate in optical filter applications.
