| Abstract | Thin films of $ZnS_{0.5}$ $Se_{0.5}$ have been prepared on glass substrate by screen printing method followed by sintering process using ZnS, ZnSe, $ZnCl_{2}.$ $H_{2}O$ and ethylene glycol as a binder. To deposit good quality films, optimum conditions have been determined. The structure, composition and optical properties of these films have been investigated as a function of sintering temperature. The layers grown below 400degC show secondary phases of ZnS, ZnSe and $ZnCl_{2}$ in conjunction with a $ZnS_{0.5}$ $Se_{0.5}$ phase. At growth temperatures above 400degC, all the secondary phases start to disappear favouring the formation of $ZnS_{0.5}$ $Se_{0.5}.$ Polycrystalline $ZnS_{0.5}$ $Se_{0.5}$ films with a strong (200) orientation were grown at a sintering temperature of 500degC. These layers have the wurtzite crystal structure. The bandgap of these films are determined by reflection spectra in the wavelength range (325 - 600) nm using Tauc relation. These films have a direct band gap. The energy band gap was found to be 2.82 eV for x = 0.5. |

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.
