The thermal behaviors of the sample glasses were observed using thermogravimetric analysis (DTA) and a -12% total mass changes was recorded during a thermal treatment from 75°C to 900°C. The Judd-Ofelt parameters (Ω2,4,6) have been computed from the experimental and theoretical oscillator strengths, as well as from the optical absorption spectra. Several important radiative properties such as radiative transition probability (AR), branching ratio (βR), emission cross section (σe) and fluorescence lifetime (τ) of the 4F3/2 → 4I11/2 transition have been obtained and compared with other glasses from previous studies. The calculations of emission cross section and quantum efficiency have shown that the 1.0 mol.% Nd3+-doped glass makes a good potential laser candidate at the 4F3/2 → 4I11/2 transition.[/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]1057 nm,Borate glass,Emission cross section,Fluorescence lifetimes,Judd-Ofelt parameters,Oscillator strengths,Radiative properties,Radiative transition probabilities[/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]1057 nm,borate glasses,radiative properties[/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/10.1109/ICICI-BME.2015.7401372[/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]
