C~~ystals of CsMgCl, doped with Tm3+ exhibit a strikingly strong up-conversion luminescence when the 'G,(D) state is pumped under pulsed excitation at 465 nm. The most intense up-conversion emissions, which appear in the near-UV, originate from the 'L(F) state at 34100 cm-'. Weaker features from the
