Resonance Raman spectra and absolute cross sections of InP/ZnSe/ZnS core/shell/shell nanocrystals have been obtained at excitation wavelengths 501.7, 457.9, 410 nm. Eight different structures having nearly the same lowest excitonic absorption wavelength but significantly stoichiometries are compared. The show phonon features attributable to both InP core ZnSe shell. largest differences among se...

Abstract To get an insight into the isotype heterojunction (IHJ) properties, influence of gamma irradiation (GI) on structural and electrical properties n-ZnSe/n-Si has been presented. The ZnSe thin films were deposited onto n-Si substrate by thermal evaporation technique. X-ray diffraction (XRD) studies revealed nanocrystalline nature with prominent (111) orientation. irradiated samples displa...

InP/ZnSe/ZnS QDs with surface fluorination treatment were fabricated and their nonlinear saturable absorption properties explored. Passive Q-switching of diode-pumped Nd:YVO 4 near-infrared laser at 1064 nm (∼1.0 μm) using InP-HF as absorber (SA) is observed.
