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

Abstract:

Erbium 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 980 nm photons, then reuptake 980 nm photons.
