Title: Effect of deposition temperature on the structural and optical properties of CdSe thin films synthesised by chemical bath deposition

Cadmium selenide thin films were synthesized on glass substrates using chemical bath technique (CBD) at temperatures 320K, 330K, 340K,and 350K. The polycrystalline nature of the material was confirmed by X-ray diffraction technique and various structural parameters such as lattice parameters, grain size, dislocation density, and micro strain. The root mean square (RMS) roughness was obtained by using atomic force microscopy(AFM), which indicated a decreasing average roughness with the decrease of the bath temperature. Optical properties were carried out by UV-Visible transmittance spectra, and the band gap energy was determined.
