Role of ambient air on photoluminescence and electrical conductivity of assembly of ZnO Nanoparticles
Manoranjan Ghosh, R. S. Ningthoujam, R. K. Vatsa +5
Effect of ambient gases on photoluminescence (PL) and electrical conductivity of films prepared using ZnO nanoparticles (NPs) have been investigated. It is observed that NPs of siz…

Characterization of doping levels in heteronuclear, gas-phase, van der Waals clusters and their energy absorption from an intense optical field
J. Jha, P. Sharma, V. Nataraju +3
A simple mass spectrometric method has been developed to quantify dopant levels in heteronuclear clusters in the gas phase. The method is demonstrated with reference to quantificat…
