| Abstract | Crystal structure of gadolinium borate Gd17.33(BO3)4(B2O5)2O16 has been refined by the Rietveld method from X-ray powder diffraction data. Gd17.33(BO3)4(B2O5)2O16 crystallizes in the monoclinic space group Cm with lattice constants a=1841.70(3), b=374.08(1), c=1419.30(3) pm and β=119.85(1)°. The structure contains two types of borate groups BO33– and B2O54– , and nine independent gadolinium atoms. IR, Raman and HREM studies supported the presence of these two different borate groups in the structure. The luminescent spectra of the Eu3+ doped material consist of several sharp lines originating from the optical transitions within the f6 configuration of the Eu3+ ions at different cation sites. |

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.
