The optical absorption measurements exhibited signature of Nd3+ absorption bands in fluorophosphate glasses showed. The spectroscopic analysis have been carried out using Judd-Ofelt parameters and oscillator strength to determine radiative properties such as radiative transition probability (AR), branching ratio (βr), lifetime (τ), emission cross-section (σe) and quantum efficiency (η). The highest emission intensity was found at 1060 nm for transition 4F3/2 → 4I13/2 under excitation wavelength of 582 nm for PANCaFN2. The emission cross section, branching ratio and lifetime were evaluated and showed 4.92 × 10−20 cm2, 0.7 and 200 μs, respectively. More importantly, the outstanding quantum efficiency of PANCaFN2 could reach to 98.92%. The addition of Nd3+ ion into fluorophosphate glass could enhance the spectroscopic properties which could play as a potential candidate for solid state applications. Theoretical optical gain evaluation and experimental calculation confirmed that PANCaFN2 had the higher gain than other samples.[/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]Doped fluorophosphate glass,Emission cross section,Fluorophosphate,Laser glass,Optical absorption measurement,Radiative transition probabilities,Spectroscopic,Spectroscopic property[/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]Fluorophosphate,Laser glass,Nd3+ ion,Spectroscopic[/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.2019.116738[/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]
