| Abstract | Summary form only given. Up to now UV solid state lasers are realised on the basis of 5d-4f transitions of Ce/sup 3+/. The aim of the work is the development of a new laser material in the UV and visible spectral range making use of 5d-4f transitions of divalent rare earth. The optical transitions between the 4f/sup n-1/-5d state and the 4f/sup n/ state involve energy levels of different parity and are therefore electric dipole allowed. Thus high transition rates are expected. Furthermore, the strong electron-phonon coupling yields broad emission and excitation bands. In the past, especially Sm/sup 2+/ and Eu/sup 2+/ ions were thoroughly investigated, whereas Tm/sup 2+/ is difficult to stabilise. In the work Yb/sup 2+/ as doping material is the focus of interest. In case of divalent incorporation the 4f-shell is completely filled and as a result no disturbing 4f-4f transitions influences the luminescence due to the 5d-4f transition. Spectroscopic data on Yb/sup 2+/-doped LiCaAlF/sub 6/ (LiCAF) and LiSrAlF/sub 6/ (LiSAF) are presented for the first time. |

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.
