Investigations of temperature-dependent photoluminescence of uncoated and silver-coated CdS quantum dots
P. Ghosh, D. Kushavah, P. K. Mohapatra +3
We report temperature-dependent photoluminescence (PL) studies and PL relaxation dynamics for uncoated and silver-coated CdS quantum dots (QDs). Room-temperature photoluminescence…

Observation of four-photon absorption and determination of corresponding nonlinearities in CdS quantum dots
P. Ghosh, E. Ramya, P. K. Mohapatra +5
Bound- and excited-state electronic nonlinearities in CdS quantum dots have been investigated by Degenerate Four-Wave Mixing (DFWM) and Z-scan techniques in the femtosecond time re…
