Photostimulated luminescence was observed in X-ray irradiated BaBrCl doped with Eu^2 + . It shows an emission band that peak at 413 nm, and two difference absorption spectra (DAS) bands that peak at - 550 nm and 67...
The optical absorption spectra of BaF2-x Clx :Eu^2+ after ultraviolet (UV) light excitation were investigated. The differences between the absorption spectra after and before excitation (DAS) were observed. The ...
