Abstract

We report on cooperative downconversion in Yb3+RE3+ (RE=Tm or Pr) codoped lanthanum borogermanate glasses (LBG), which are capable of splitting a visible photon absorbed by Tm3+ or Pr3+ ions into two near-infrared photons. The results indicate that Pr3+Yb3+ is a more efficient ion couple than Tm3+Yb3+ in terms of cooperative downconversion. We have obtained a highest quantum yield of 165% and 138% for Pr3+Yb3+ and Tm3+Yb3+ codoped LBG glasses under 468nm excitation, respectively. However, ultraviolet light excitation to the charge transfer band of Yb3+ does not result in quantum splitting as rapid relaxation from the charge transfer band to 4f13 levels of Yb3+ dominates.
