| Abstract | Copper manganese oxide nanostructures were spray pyrolytically deposited on glass substrates with Cu:Mn concentrations 0.05:0.05, 0.1:0.1, 0.15:0.15, 0.2:0.2 M at the substrate temperature of 300 °C. The peak positions of the films deposited with precursor concentration 0.15:0.15 M confirmed the monoclinic CuMnO$_{2}$ single phase structure. Surface morphology of the films was analyzed and then the chemical environment about the presence of Cu, Mn and O was analyzed in a photoelectron spectrometer. The binding energies of Cu-2p doublet positioned at 932.5 and 952 eV, represented the existence of Cu$^{1+}$ in the films. Additional peak located at binding energies 638.8 and 650.3 eV corresponds to the Mn-2p of the film. The direct band gaps of the film were estimated and found near to 3.7 eV. The room temperature electrical conductivity of the film was 0.5577 mho/cm, which was comparatively high in the ABO$_{2}$ group of compounds. The ethanol gas sensing property of the CuMnO$_{2}$ films were measured at RT, 100 and 200 °C temperatures and the sensitivity was analysed and compared. |

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.
