| Abstract | In this work, undoped and boron doped nanostructure SnO$_{2}$ films were synthesized by a simple ultrasonic spray pyrolysis method onto quartz substrate at 315 °C and then annealed at 550 °C. The structure, morphology, optical, electrical and photoluminescence properties of the films were studied. The X-ray diffraction results confirmed that the boron doped SnO$_{2}$ films were tetragonal phase with preferred orientation in (110) plane and the scanning electron microscopy images showed obvious morphology change caused by boron doping. The Fourier transform infrared spectrometer (FTIR) and Hall effect measurement revealed the boron ions preferred occupying the interstice of SnO$_{2}$ lattice to replacing the tin ions. The lowest resistivity was 3.525 × 10$^{−3}$ Ω cm with 4 at.% boron doping. The boron doping improved the average optic transparency in visible (400–800 nm) range from 83.97 to 93.28 %. The band gaps of the films were widened from 4.09 to 4.23 eV and then decreased. Boron doped SnO$_{2}$ films showed a strong emission peak around 364 nm and weak blue–green emission peak around 457 nm. The results confirmed boron doped SnO$_{2}$ film can be suitable for applying in nano-optoelectronics devices. |

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.
