The vacuum ultraviolet spectroscopic properties of GdOCl:Re3+ (Re3+=Ce3+, Tb3+, Eu3+, and Dy3+) are investigated in detail for the first time. The host absorption band is determined to be around 179nm, and the f–d transition bands as well as the charge transfer bands are assigned. Upon 179nm excitation, Re3+ (Re3+=Ce3+, Tb3+, Eu3+, Dy3+) ions shown their characteristic emissions. Energy transfers...
The VUV-UV spectroscopic properties of Ce 3+ in Ba 2 Mg(BO 3 ) 2 , Ba 2 Ca(BO 3 ) 2 and Sr 2 Mg(BO 3 ) 2 were compared, and the relation between the energy of the 4f→5d transition of Ce 3+ and the coordination environments of substituted alkaline earth ions was discussed. The chromaticity coordinates of Ce ...
