| Abstract | Summary form only given. In this paper, cerium-doped zinc oxide films (ZnO:Ce) were deposited by reactive chemical pulverisation spray pyrolysis technique using zinc and cerium chloraids as precursors at temperatures up to 500 /spl deg/C. The effect of Ce concentration on the structural, electrical and optical properties of ZnO thin films were carefully investigated. These films were studied using four probe method, X-ray diffraction and photoluminescence measurement. The X-ray diffraction analysis indicates that all films are polycrystalline in nature and clearly shows the appropriate incorporation of Ce atoms in the ZnO films. The chemical composition of the films as determined by energy dispersive spectroscopy is also reported. The ZnO layers display three major PL peaks: an UV near-band edge emission peak at 378 nm, a green emission around 510 nm, and a red emission around 650 nm. The green emission and red emission are probably associated with the oxygen vacancies and interstitial Zn ions in the ZnO lattice. The influences of Ce concentration on the nonlinear optical properties using THG technique will be presented. |

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.
