Tīmeklismodes specific to ZnS materials on the Raman spectra at about 260 and 345cm−1 and on Fourier-transform infrared ... ZnS is found in two distinct crystalline phases: zinc-blende (cubic phase) and wurtzite (hexagonal phase), with 0123456789().: V,-vol. 223 Page 2 of 8 Bull. Mater. Tīmeklis2024. gada 6. nov. · The surface shallow defect related emissions of ZnS were quenched with NaCMC capping. A very good enhancement in photoluminescence intensity was observed with NaCMC-capped sample compared to uncapped ZnS. FTIR and Raman studies suggested that capping action of NaCMC onto ZnS takes place …

TīmeklisThe present paper focuses on the properties of the p–Si/ ZnSxSe1−x (0 ≤ x ≤ 1) heterojunctions in photodetector applications. The heterostructures were fabricated by depositing ZnSSe on Si wafer using the thermal co-evaporation technique with ZnS and ZnSe powders. The GIXRD study showed that films were in cubic phase, and the … Tīmeklis2024. gada 1. dec. · Raman spectra of the ZnS crystal before (dashed line) and after (dotted line) multi-He ion implantation.

Tīmeklis2015. gada 1. sept. · A comprehensive Raman resonance scattering study of ZnS x Se 1−x (ZnSSe) solid solutions over the whole compositional range (0 ≤ x ≤ 1) has been carried out using 325 and 455 nm excitation wavelengths. The Raman scattering intensities of LO ZnS-like and ZnSe-like phonon modes, corresponding to pure S and … TīmeklisThe Raman spectroscopy is an important tool to study the structure and phase transitions of different materials. Raman studies show that compared with the Raman modes of undoped ZnS NPs the vibrational modes in ion-doped ZnS nanostructures are shifted towards lower or higher frequencies [32,40,41,42,43]. The origin for this shift … Tīmeklis2006. gada 26. dec. · Raman spectra of ZnS:Cu,Cl powders show a structural transition from hexagonal to cubic and a crystal growth with increasing Cu addition (> 400 … generac 5500 air filter
