Abstract:

Simultaneous emission lines around 1.05 mu m, 1.3 mu m, 1.8 mu m, 2.1 mu m and 2.7 mu m have been observed in Li7La3-xNdxHf2O12:Ho3+ (x = 0.00-0.15) under 808 nm laser diode excitation. Near-infrared luminescence due to holmium ions with residual concentration in the Li7La3Hf2O12 host has been studied. The intensity of 2.1 and 2.7 pm lines associated with (5)1(7) -> I-5(8) and I-5(6) -> I-5(7) transitions in Ho3+ depends on the neodymium codopant concentration. This result indicates that Nd3+ ions can be potentially used as sensitizers for Ho3+ ions to stimulate the intense near-infrared emission in this system. Possible energy transfer mechanisms between lanthanide ions have been briefly discussed. (C) 2017 Elsevier B.V. All rights reserved.
