摘要：

To obtain Vacuum ultraviolet (VUV) phosphors with quantum efficiencies higher than 100%, the concept of downconversion is used. In a downconversion process a VUV photon is split into two visible photons by making use of energy transfer between different rare earth ions. Two examples of downconversion couples are discussed, viz. the Gd3+-EU3+ couple and the Er3+-Gd3+-Tb3+ system. (C) 2000 Elsevier Science S.A. All rights reserved.
