Feb 1, 2011 · Zinc sulfide (ZnS) is one of the first semiconductors discovered. It has traditionally shown remarkable versatility and promise for novel fundamental …

Dec 14, 2010 · The authors carefully examine the green PL properties of the ZnS nanoparticles and nanospheres in the range of 400–650 nm and infer experimentally that the green PL is closely related to zinc vacancies.

Nov 1, 2006 · The room-temperature photoluminescence (PL) of copper doped zinc sulfide (ZnS:Cu) nanoparticles were investigated. These ZnS:Cu nanoparticles were synthesized by a facile wet chemical method, with the copper concentration varying from 0 to 2 mol%.

ZnS is one of the first semiconductors discovered that has shown the remarkable properties that can be exploited for versatile applications including field emitters, electroluminescence, electro catalyst, biosensors.

The as‐prepared ZnS QDs are characterized by photoluminescence (PL), UV–vis absorption, Fourier transform infrared (FTIR), and X‐ray powder diffraction (XRD).

Dec 1, 2018 · Ultra Violet-Visible (UV-Vis) spectroscopy and Photoluminescence (PL) measurements were performed to study their optical properties at room temperature. Characteristic blue emission was observed for the pure ZnS.

The room temperature photoluminescence (PL) spectra of Mn2+-doped ZnS nanocrystalline showed extra peaks in yellow-orange and red region in comparison of pure ZnS.

Dec 17, 2014 · The resultant CIS-ZnS QDs exhibit highly efficient and well-resolved Mn 2+d-d emission with a PL QY up to 66% and a surprisingly long lifetime up to ~3.78 ms, which is nearly two times longer...

Dec 10, 2019 · The ZnS quantum dot solid based UV sensor shows good photocurrent response and a maximum responsivity of 0.31 (A/W) at a wavelength of 390 nm, is not only competitive when compared with previous...
