All rights reserved. Lithium aluminium phosphate glasses doped with samarium oxide were prepared by melt-quenching technique and investigated their physical, optical and luminescence properties. The result of physical properties indicated that the density and the molar volume of glass samples were increased with an increase of Sm 2 O 3 content. The absorption spectra of glass samples were recorded in the wavelength range of 250-2000 nm, these glasses have shown strong absorption bands in the visible (Vis) and near-infrared (NIR) region at 401 and 1232 nm. The emission spectra of glasses, excited with 401 nm excitation wavelength showed four emission bands centered at 561, 597, 644 and 704 nm. From Judd-Ofelt analysis, the J-O parameter (Ω 2 , Ω 4 , Ω 6 ), radiative transition possibility (A R ), stimulated emission cross-section (σ(λ p )) and branching ratios (β R ) were indicated that the glass samples an interesting potential for using glass as laser medium with 597 nm emitting.[/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][/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]Judd-Ofelt analysis,Luminescence,Phosphate glass,Samarium ion[/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 would like to thanks National Research Council of Thailand (NRCT), Nakhon Pathom Rajabhat University (NPRU) and Suan Sunandha Rajabhat University (SSRU) for funding and supporting this research.[/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.matpr.2018.04.052[/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]
