| Abstract | An investigation on Fe-doped ZnO (Zn1-xFexO, x=0, 0.03, 0.06 and 0.09mM) nanopowder have been synthesized by co-precipitated method annealed at 550°C were reported. The structural, morphological and optical properties of the samples were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectra (EDS) analysis, Atomic Force Microscopy (AFM), UV-Visible spectroscopy, and photoluminescence (PL) techniques, Fourier transform infrared (FTIR) spectroscopy. The XRD spectrum shows all the samples are hexagonal wurtzite structure. The presence of functional groups and chemical bonding are confirmed by FT-IR. The PL spectra of the Zn1-xFexxO systems show that the shift in near band edge (NBE) UV emission from 344.54 to 364.21nm and a shift in green band (GB) emission from 484 to 540nm which conforms the substitution of Fe into the ZnO lattice. UV-Visible measurement showed a decrease in the energy gap with increasing Fe content, probably due to an increase in the lattice parameters. It is also found that these results are in good agreement with other calculated and experimental results. |

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.
