Braad band emission which bas two peaks at 290 nm and 420 nm was observed in Yb3+-activated LuP04 and YPO4. It is shown that thΓ―s emission is due to a charge-transfer type transition, i.e. the reverse process of the charge-transfer absorption of Yb3+ ions It is well known that some of the transition
