A theoretical study of optical properties of CdS quantum dots and evaluation of optical band gap of CdS nanoparticles, particle size and temperature dependent intensity of PL - spectra as a function of photon energy (jcbsc.org)
The measured optical band gap of these samples matches the predicted dependence as a function of the sample's order parameter as measured by Raman scattering and both x-ray and electron diffraction, and hence allows for the possibility of tuning the band gap of ZnSnN2 without having to alloy with other material systems.

Previous large - area searches have been incomplete for L / T transition dwarfs, because these objects are faint in optical bands and have near - infrared colors that are difficult to distinguish from background stars. (arxiv.org)
