| Abstract | A series of single-component blue-, white- and orange-emitting phosphors have been developed based on the BaY2Si3O10 host via the Ce3+/Eu3+, Tb3+/Eu3+, Ce3+/Tb3+, and Ce3+/Tb3+/Eu3+ couples and the energy transfer among them has been discussed in detail. A terbium bridge model via Ce3+–Tb3+–Eu3+ energy transfer has been studied and verified. The phase structures, photoluminescence (PL) properties, decay curves, PL thermal stability, and the energy transfer mechanism were investigated in this paper. The emission colors of the phosphors can be tuned from blue (0.1501, 0.0805) to white (0.3230, 0.3140) and eventually to orange (0.4496, 0.3537) through the corresponding Ce3+–Tb3+–Eu3+ energy transfer. Moreover, thermal quenching luminescence results reveal that BaY2Si3O10:Ce3+,Tb3+,Eu3+ exhibits good thermal stability. The above results indicate that the phosphors may be potentially used as single-component multi-color or white emission phosphors for application in white light emitting diodes (w-LEDs). |

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.
