摘要：

Up-conversion luminescence phenomenon of crystalline and noncrystalline ErP(5)O(14) induced by about 650 nm laser are researched and analysed carefully. Not only two-photon but also three-photon up-conversion luminescence are found. The up-conversion mechanism of crystalline ErP(5)O(14) is mainly the nonresonant up-conversion energy transfer, which is mainly achieved directly through a kind of coupling state of quasi-clusters of rare-earth ions and do not exchange the phonon energy with the crystal-lattice base to offset the energy mismatch. The mechanism, to our best knowledge, has nor been reported yet. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
