β-Ga2O3 is an ultra-wide bandgap semiconductor (Eg~4.8 eV) of interest for many applications, including optoelectronics. Undoped Ga2O3 emits light in the UV range that can be tuned to the visible region of the spectrum by rare earth dopants. In this

Electron Spin Resonance investigations allow to attribute a broad absorption band below the band-to-band transition of ZnO:Co to photoionization transitions of Co-ions. This absorption, with the onset at about 2.4–2.6 eV, is due to cobalt rechargin

Based on two-colour spectroscopy, we identify origin of infrared emissions in Cr doped ZnSe. Near infrared emission at about 0.98 μm is related to Cr 2+ intra-shell process. Optical memory effect is observed related to metastability of light induced
