Chemical bath deposition technique has been used to synthesize metal selenide (MSe) thin films. MSe(M= Sn, Zn, Pb, Cd and Cu) thin films are deposited on glass substrates in an aqueous alkaline medium using sodium selenosulphate as Se2- ion source. The quality and the crystalline size of the MSe thin films has been calculated by X-ray diffraction (XRD). Information of the strain and the particle size has been obtained from the full widths at half maximum (FWHM) of the diffraction peaks. Solar selective coatings, solar control, photoconductors, solid state and photoelectrochemical solar cells, optical imaging, hologram recording, optical mass memories etc. are some of the applications of metal selenide thin films. In the present review paper we have discussed in detail, how the particle size varies by changing the deposition parameters like substrate temperature and deposition time and also describe the effect of annealing
