Ba0.2Sr0.8TiO3 (Barium Strontium Titanate) doped of chlorophyll of spinach and papaya leaves was grown on a p-type silicon substrate (100). Film growth method uses a chemical solution deposition method with a spin coating technique. This deposition technique is an application of centripetal force so that the solution can be spread evenly on the film. The solution is dripped, three drops of solution three times, where the spin coating reactor’s rotational speed is 8,000 rpm for 30 seconds with a delay between repetitions of 60 seconds. The annealing process is carried out as a high-temperature heating step which aims to restore the physical and crystalline properties of the film which may change during the film growth process. The specified annealing temperature is 850oC with a holding time of 8 hours. The effect of chlorophyll doping was observed by applying variations in chlorophyll concentration of spinach leaves and papaya leaves which were 0%, 2.5%, and 5%.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Annealing process,Annealing temperatures,Chemical solution deposition method,Chlorophyll concentration,Crystalline properties,Deposition technique,High temperature heating,Micro Raman Spectroscopy[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We gratefully acknowledge the funding from USAID through the SHERA Centre for Development of Sustainable Region (CDSR) program.
