Enhanced three-photon near-infrared quantum splitting in β-NaYF4:Ho3+ by codoping Yb3+

An efficient three-step sequential three-photon near-infrared (NIR) quantum splitting (QS), involving the emission of three NIR photons from an absorbed ultraviolet (UV) photon in β-NaYF4:Ho3+, has been demonstrated. Codoping Yb3+ can increase the NIR emissions significantly through the first- and s...
