中文摘要	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 468 nm 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 4f(13) levels of yb3+ dominates.
