Fabrication of ZrO2:Er3+ Nanocrystals and the Researching of Emitting Mechanism

AbstractErbium doped ZrO2 (ZrO2:Er3+) nanocrystals are fabricated by a butadinol low thermal crystallization method.The emitting mechanism of Er3+ is researched. Er3+ level of the stark split were calculated with the crystals field theory, and the two levels of the spectral lines have been further recognition. It can be indicated that 980nm stimulates Er3+ upconverting. One process is continuous absorption of two 980nm photons. Another is electronic transfer to metastability level after absorbing 980nm photons, then reuptake 980nm photons
