| Abstract | The paper is devoted to investigate some doped oxide crystals: diphosphate M/sup I/Me/sup III/P/sub 2/O/sub 7/ (M = Na, K. Cs; Me = Al, In) crystals doped with Cr/sup 3+/ ions, potassium titanyl orthophosphate KTiOPO/sub 4/ crystals doped with Cr/sup 3+/, Nd/sup 3+/ and Eu/sup 3+/ ions, silicate akermanite Me/sub 2/SiO/sub 4/ (Me = Ca, Mg) crystals doped with Cr/sup 3+/ ions. Possibility of the impurity ions to form at the same crystal lattice various charge states must be taken into account at a design of the complex oxide materials on the contrary to the other simple oxides, f.e. Al/sub 2/O/sub 3/ crystals, where the chromium ions are arranged mainly in the Cr/sup 3+/ charge state. Luminescence spectra of the noted crystals were investigated. The energy schemes of the electron states of the impurity ions in the various crystal matrices are considered taking into account the Tanabe-Sugano diagram and the known schemes of electron levels of rare earth ions. Values of Dq and /spl Delta/E/sub TE/ were calculated for various crystal lattices doped with Cr/sup 3+/ ions. Some spectroscopy parameters were estimated for the most intensive transitions in spectra of the studied materials. |

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.
