摘要：
Mn2+ doped In2S3-SiO2 nanocomposite thin films were synthesized by sol-gel technique. The films were annealed in air at different temperatures (473-623 K) and characterized by optical, microstructural and electron spin resonance (ESR) study. Optical transmittance study revealed the manifestation of quantum size effect while ESR indicated the presence of manganese in indium sulphide as dispersed dopant rather than manganese cluster.
