Abstract:

An efficient broadband excited near-infrared to visible up-conversion is observed in LaF3:Ho3+ as the result of a two-wavelength excitation. The visible up-conversion emission intensity is greatly enhanced upon simultaneous excitation at 970 nm and 1150 nm, due to an energy transfer up-conversion mechanism. Multi-wavelength excitation based on the ground-state absorption, excited-state absorption, and phonon-coupled absorption of rare-earth ions results in an efficient broadband excited up-conversion emission, which may provide a new approach to fully harvest NIR solar energy and has potential application in solar cells. © 2013 The Royal Society of Chemistry.
