| Abstract | This paper presents a study on the spectroscopic and radiative properties of Nd3+ ions in sodium-borate glasses (B2O3-Na2O-PbO-ZnO-Li2O). 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. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
