摘      要：Oxvfluoride glass ceramic doped with doped with Er^(3+)/Yb^(3+)was *** earth ions are doped into fluoride nanocrystals according to x-ray diffractive *** enhanced red emission of Er^(3+)/Yb^(3+)in the fluoride nanocrystals,excited by xenon lamp ta 449nm,is investigated and analyzed by cooperative quantum cutting *** cross relaxation appears from^(4)F_(5/2)→^(4)F_(9/2)to^(4)I_(15/2)→^(4)I_(13/2)because of the nearer distance of rare earth ions and the larger absorption section of^(4)F_(5/2)→^(4)I_(13/2)in the quantum *** results in two emissions of^(4)F_(9/2)→^(4)I_(15/2)and^(4)I_(13/2)→^(4)I_(15/2).This implies that a 449nm photon could dissolve into two emiswith wavelength 665nm and *** could be an effective way to obtain 1530nm emission for optical communication.
