AbstractThe 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 179 nm, and the f-d transition bands as well as the charge transfer bands are assigned. Upon 179 nm excitation, Re3+ (Re3+ = Ce3+, Tb3+, Eu3+, Dy3+) ions shown their characteristic emissions. Energy transfers from Gd3+ to Re3+ ion were observed. A broad band ranging from 350 to 400 nm corresponding to the d-f transition of Ce3+ is observed. Eu3+ has typical red emission with the strongest peak at 620 nm; Tb3+ shows characteristic transition of D-5(3,4) -> F-7(j), and its spin-forbidden and spin-allowed f-d transitions in VUV region are calculated with Dorenbos' equations, these calculated values agree well with the experimental results. Dy3+ presents yellow emission (F-4(9/2) -> H-6(13/2)) with the strongest peak at 573 nm. (C) 2015 Elsevier B.V. All rights reserved.
