Electrochemical supercapacitor performance of SnO2 quantum dots
V. Bonu, B. Gupta, S. Chandra +3
Metal oxide nanostructures are widely used in energy applications like super capacitors and Li-on battery. Smaller size nanocrystals show better stability, low ion diffusion time,…
Invoking forbidden modes in SnO_2 nanoparticles using tip enhanced Raman spectroscopy
Venkataramana Bonu, A. Das, A. K. Sivadasan +2
Raman forbidden modes and surface defect related Raman features in SnO_2 nanostructures carry information about disorder and surface defects which strongly influence important tech…
Surface functionalization enhanced magnetism in SnO_2 nanoparticles and its correlation to photoluminescence properties
Venkataramana Bonu, Arindam Das, Manas Sardar +2
High value of magnetic moment 0.08 emu/g at room temperature for SnO_2 nanoparticles (NPs) was observed. Surface functionalization with octadecyltrichlorosilane (OTS) enhanced the…
Photoluminescence of oxygen vacancies and hydroxyl group surface functionalized SnO_2 nanoparticles
Venkataramana Bonu, Arindam Das, S. Amirthapandian +2
We report, for the first time, the luminescence property of the hydroxyl group surface functionalized quantum dots (QDs) and nanoparticles (NPs) of SnO_2 using low energy excitatio…
Influence of in-plane and bridging oxygen vacancies of SnO_2 nanostructures on CH_4 sensing at low operating temperatures
Venkataramana Bonu, A. Das, Arun K Prasad +3
Role of 'O' defects in sensing pollutant with nanostructured SnO_2 is not well understood, especially at low temperatures. SnO_2 nanoparticles were grown by soft chemistry route fo…
