| Abstract | Ag nanoparticles were fabricated on Si substrates by radio-frequency magnetron sputtering and thermal annealing treatments. It was found that Ag nanoparticles are ellipsoid at low annealing temperature, but the axis ratio decreases with the increase of annealing temperature, and a shape transformation from ellipsoid to sphere occurs when the temperature increases to a critical point. The experimental results showed that the surface plasmon resonances depend greatly on the nanoparticles’shape and size, which is in accordance with the theoretical calculation based on discrete dipole approximation. The results of forward-scattering efficiency (FSE) and light trapping spectrum (LTS) showed that Ag nanoparticles annealed at 400°C could strongly enhance the light harvest than those annealed at 300 and 500°C, and that the LTS peak intensity of the former is 1.7 and 1.5 times stronger than those of the later two samples, respectively. The conclusions obtained in this paper showed that Ag ellipsoid nanoparticles with appropriate size is more favorable for enhancing the light trapping. |

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.
