The phosphors were prepared from precursors containing boric acid, urea, poly(ethylene glycol) (PEG) and SiO2 nanoparticles. The sample exhibited a single, distinct and broad photoluminescence (PL) emission band, the color of which varied from blue (480 nm) to green (522 nm). Adding SiO 2 nanoparticles into the precursor homogenizes the spatial distribution of luminescent centers throughout the sample and increases the quantum yield up to 6-fold (for 3 wt% of SiO2 nanoparticles) compared with that of the sample without SiO2 nanoparticles. The BCNO/SiO2 nanocomposite has potential applications in white LEDs. © 2013 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]Low temperatures,Luminescent centers,Oxynitrides,Phosphor materials,Photoluminescence emission,Silica nanoparticles,White LED[/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]Boron carbon oxynitride (BCNO),Non-rare earth phosphor,Silica nanoparticle[/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/10.1016/j.jlumin.2013.12.033[/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]
