摘要：

An analysis of infrared to visible upconversion in Ho3+:BaY2F8 is given. Excitation at 888 nm into the I-5(8) --> I-5(5) transition leads to intense visible emission in the blue, green and red spectral range. Based on the energy levels of Ho3+ in BaY2F8, and the pump intensity dependencies of the observed emissions, an excitation scheme is presented. (C) 2001 Elsevier Science B.V. All rights reserved.
