摘要：
In this paper, we demonstrate a simple and efficient method for synthesis of beta-indium sulphide (In2S3) nanoparticles embedded in an ionomer matrix (nafion membrane). The influence of reaction temperature on structural, compositional and optical properties of these films were analysed using X-Ray Diffraction, EDAX, UV-Vis absorption spectroscopy and photoluminescence studies. Average particle diameter was estimated using modified effective mass approximation method. Absorption spectra of In2S3 nanoparticles show blue shift compared to bulk In2S3, indicating strong quantum size confinement effects. PL emission in the wavelength range 530-600 nm was recorded using a 488 nm line from an Ar+ laser as the excitation source.
