Energy Gap Measurement of CdS Nanoparticles Fabricated by SILAR Technique

In this paper, CdS nanoparticles deposited on glass substrate by SILAR technique at room temperature. For this purpose, substrates are taken in solutions for 1.5, 3, and 4.5 min. Optical absorption coefficient of layers are measured and their band gaps are calculated. SEM images show nanoparticles sizes are between 37.4to 50.5 nm. Also our results show that energy gap increases with decreasing particle size
