SnO2 Quantum Dots as Methanol Sensor Abhigyan Ganguly, Sandipan Biswas, Nitai Paitya, Siddhartha S. Nath Semiconductors, 2026 Tin oxide (SnO2) quantum dots were synthesized via a thermal quenching method and evaluated for methanol vapor sensing. Characterization confirmed their nanoscale size (~10–12 nm). The sensor exhibited high sensitivity, rapid response, and recovery, with optimal performance at 250°C. Enhanced surface area and efficient charge transfer mechanisms enabled effective detection across various methanol concentrations. These results demonstrate that SnO2 quantum dots are promising candidates for fast, reliable, and low-cost methanol gas sensing applications.

Study of PbS Nanomaterial Sensitized ZnO based Solar Cell using SCAPS-1D Simulator Vishal Jha, Somnath Dasgupta, Abhigyan Ganguly 2023 International Symposium on Devices Circuits and Systems Isdcs 2023 Conference Proceedings, 2023 PbS is generally used as the preferred material for sensitizing layer in solar cells due to its wide range of band-gap tunability. As the light absorption in in sensitizing layer of solar cell depands on the band gap of the material, hence nano-crystalline PbS has a wider range of light absorption starting from the UV up to the NIR regions of the solar spectrum. In the present study we have simulated a FTO/ZnO/PbS/Al type structure using SCAPS-1D simulator, and the Current density curve is obtained for voltage characteristics is studied. With an aim of studying the effect of the thickness of the sensitization layer on the working of solar cell, the thickness of the nano-crystalline PbS layer is varied and the values of the essential solar cell factorsare acquired for the simulated solar cell.

Copper Ion Irradiated SnO2 Quantum Dots for Higher Electroluminescence in Nano Light Emitting Device Abhigyan Ganguly, Siddhartha Sankar Nath IEEE Sensors Letters, 2022 SnO2 quantum dots have been synthesized using simple low cost chemical quenching method and they are exposed to 100MeV swift heavy ions of copper, with doses of 1 × 1011 and 2 × 1011 ions/cm2. The samples are characterized using standard characterization instruments such as UV/VIS spectroscopy, X-ray diffraction study (XRD), Raman spectroscopy, and high resolution transmission electron microscopy (HRTEM). The irradiated as well as the pristine quantum dots of SnO2 are introduced into ZnO on TCO substrate to fabricate different nano light emitting device (LED). The electroluminescence (EL) variation with change in supply voltage is studied at room temperature. An enhancement in EL intensity has been obtained with increase in ion irradiation doses in quantum dot LEDs, when compared to pristine one. Also, the almost instantaneous response time and linear variation of emission intensity with voltage makes these low doses of swift heavy ion irradiated SnO2 quantum dots a more suitable material for EL-based devices.
