Synthesis and characterization of silver doped calcium chromate spinel Nano- particles and Ca effect on its band gap and optical properties

Silver chromates catalysts have newly been discussed by different preparation and utilization approaches. The results of all discussion explain that silver chromates is a proficient catalyst using for catalyses programmes at national and commercial level including worldwide environmental control of pollution. Various applications of silver chromates in energy clean, laboratory. Eco-friendly approach naming sol-gel is used to get final sample and characterized by SEM, XRD, EDS and photoluminescence. Final sample approach is affected by various parameters. Furnance was used to sinter at 750-900 o C for 4 hours.I intended 1.56 eV band gap value, 28.881 nm crystalline size for doped sample and EDS describes silver was successfully doped and emerged completely.
