In this work, CNDs were synthesized from a precursor consisting of citric acid [C6H8O7] as carbon source and urea [(NH2)2CO] as nitrogen source through a microwave-assisted method. The heat energy supplied during the microwave process was controlled. Further, we studied the effect of citric acid mass on the photoluminescence (PL) properties of the CNDs by varying its percentage in the precursors. The optimum luminescence intensity was obtained from the sample that was produced from 1.2 wt% citric acid mass. It had a single emission band with bright yellow luminescence.[/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]Low cytotoxicities,Luminescence intensity,Microwave process,Microwave-assisted methods,Nitrogen sources,Phosphor materials,Photoluminescence properties,Yellow luminescence[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/739/1/012045[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
