| Abstract | In this work, pulsed laser annealing (PLA) was preformed on ion-beam-synthesized $Ag-SiO_{2}$ nanocomposites to improve the FE properties of these samples by modifying the size and distribution of the Ag nanoclusters. The PLA was preformed using a 248 nm KrF excimer laser. Multiple pulses, with durations of 25 ns, at an energy density of 250 mJ/cm were accumulated onto the sample. The FE properties of the samples were studied in a high vacuum chamber, with a base pressure better than $5x10^{-4}$ Pa. The current-electric field (I-F) characteristics were measured using a "sphere-to-plane" electrode configuration, with a 5 mm diameter stainless-steel ball anode. The applied electric field was obtained by dividing the applied voltage by the gap distance and the threshold field $(F_{th})$ and is defined as the field strength when an emission current of 1 nA is achieved. The microstructure and the surface morphology of these samples are determined by the cross-section transmission electron microscopy (XTEM) and atomic force microscopy (AFM) measurements, respectively. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
