摘要：

The undoped stoichiometric materials LiTbP4O12 and LiEuP4O12 show effective green Tb3+ and red Eu3+ luminescence, respectively. Both systems are fully mixable, which offers the possibility of examining the energy transfer from Tb3+ to Eu3+ in the complete system of LiTb1-xEuxP4O12. As the distance of the rare earth ions is large enough to exclude exchange interaction in these materials, only multipolar interaction is to be expected. Dealing only with forbidden f-f transitions it is possible to produce both Tb3+ and Eu3+ luminescence at the same time having a suitable Eu3+ concentration. (C) 2004 Elsevier Ltd.
