When both Eu and Ca ions were added, Ca 3B 2O 6:Eu phosphors could be synthesized via a straightforward process using a liquid precursor. The photoluminescent spectra of Ca 3B 2O 6:Eu phosphors exhibited a red emission at 611 nm under 254 nm excitation, and the internal quantum efficiency reached 41.5% when the concentration of Eu ion was fixed at an optimal condition of 0.13 M. © 2012 Elsevier B.V.[/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]Internal quantum efficiency,Liquid precursors,Optimal conditions,Oxide materials,Photoluminescence performance,Photoluminescence properties,Photoluminescent spectra,Red emissions,Red emitting phosphor[/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]Oxide materials,Phosphors,Photoluminescence properties,Quantum efficiency,Red emission[/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]The authors thank the Japan Society for the Promotion of Science (JSPS) for a doctoral fellowship (Yutaka Kaihatsu).
