Crystals of Zinc Iodate (ZI) were grown by a basic gel strategy utilizing single diffusion method. The optimum growth conditions were established by various parameters, for example, pH of gel solution, gel concentration, gel setting time and concentration of reactants. The crystals were described utilizing XRD, SEM and Photo glow. Good quality crystals with various morphology and habits are acquired and detailed in this. Un doped and X-(Cu, Al and Zn) doped lead iodide crystals have been grown by gel procedure. Interestingly, slight films of these gel grown crystals have been set up of various thicknesses by vacuum thermal evaporation procedure on glass substrates (800 C). These films are smooth, uniform, glue and reflecting. Optical and basic investigations of these meager films were done. Measurements of absorption coefficients have been done and detailed. True to form, the optical vitality hole decreases with expanding dopant concentration, yet in the event of Al doped dainty films optical vitality hole increments in the current examination. The flimsy films are poly crystalline in nature and crystalline increments subsequent to doping however decreases when the thickness expanded (above 3000ǻ). The absorption edge shifts towards the higher wavelength side and gets more extensive as the doping concentrations were expanded. X-beam diffractograms and Scanning Electron Microscopy were employed on these dainty films. The lattice parameters and the [h, k, l] values practically matching with the ASTM information for lead iodide.
