Paper Abstract

In this work we present a detailed analysis of the room temperature infrared to visible upconversion in Nd3+-doped KPb2Br5 crystal by using both steady-state and time-resolved luminescence spectroscopy. The study includes one photon absorption and emission spectroscopy and lifetime measurements for the visible and infrared fluorescence, and infrared to, blue, green, orange, and red upconversion processes. The possible upconversion mechanisms are discussed in terms of excitation spectra, excitation power dependence, and lifetimes of the upconversion emissions.
