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