| Abstract | Nanosized Ce-doped lutetium aluminium garnet (LuAG:Ce) phosphors have been synthesised by a solvothermal method using ethylenediamine as the solvent and metal nitrates as the starting materials. The phase development, the morphology and the luminescent properties of the prepared phosphors were investigated with X-ray diffractometry, transmission electron microscopy and photoluminescence spectra, which showed that phosphors of high phase purity resulted after heating for 8 h at a low temperature of 230oC. This powder possesses good dispersivity, suffers little or no aggregation and has an average grain size of 220 nm with narrow size distribution, hence, it may be exploited for the fabrication of LuAG:Ce optical ceramics. Its excitation and emission spectra have also been examined, which confirms the transitions between the 4f and the 5d states of the Ce3+ ions as the photoluminescence mechanism. The photoluminescence decay showed almost identical components compared with the LuAG:Ce single crystal, which further proves that the obtained nanosized phosphors have been well crystallised. |

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.
