Abstract
Typical of trivalent impurities, Er3+ ions have a strong tendency to enter crystals of CsMgCI3, CsMgBr3 and CsCdBr3 in pairs to form Er3+–vacancy–Er3+ centers. A strong visible to UV up-conversion luminescence is observed from Er3+ containing crystals when the 4S3/2(E) excited state is pumped by a pulsed laser (545 nm–550 nm). The upconversion emissions arise primarily from doubly excited Er3+–vacancy–Er3+ centers via the pathway shown below.
