Enhanced optical properties of <i>β</i>-Ga₂O₃-_<em>x</em>S_<em>x</em>S: A DFT study حسب G.B. Eshonqulov (22927297)

"…Consequently, the absorption intensity in the visible and UV ranges of the spectrum increases by more than an order of magnitude, depending on the level of doping, with a clear red shift. …"

Investigation of the structural, optical and gas sensing properties of PANI coated Cu–ZnS microsphere composite حسب Hemalatha Parangusan (6556133)

"…The emission peaks obtained in photoluminescence spectra confirm the presence of surface defects in the prepared composite. The UV-DRS study shows that the bandgap of the samples is found to decrease for the PANI/Cu–ZnS composite compared to the pure Cu–ZnS sample. …"
