| Abstract | Strong absorption bands at 280, 385, and 640 nm; a pulsed cathodoluminescence band with peaks at 325 and 520 nm and a dip at 385 nm; and a structured luminescence band in the range of 591–711 nm composed of four pair lines and having a dip near 640 nm have been observed in the spectra of yttrium-aluminum garnet ceramics activated with ytterbium (10 mol %) and subjected to vacuum sintering at a temperature of 1800°C. It is shown that these spectral features are absorption and luminescence bands of divalent ytterbium ions with the 4f $^{13}$6s electron configuration of the ground state. These ions occupy the cubic site that is formed under conditions of oxygen deficit and disappears when the latter is removed during annealing ceramics in air. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
