2.7 μm emissions in Er 3+ : NaYF 4 embedded aluminosilicate glass ceramics
Source abstract
Abstract
Abstract Er 3+ doped NaYF 4 transparent aluminosilicate glass ceramic was prepared. X-ray diffraction and transmission electron microscopy confirmed the formation of NaYF 4 nanocrystals in glass matrix. Absorption spectra and Judd–Ofelt intensity parameters demonstrated the incorporation of Er 3+ into NaYF 4 nanocrystals. 2.7 μm emission due to the transition of 4 I 11/2 → 4 I 13/2 was achieved upon the excitation of a 980 nm laser diode. Visible emission spectra, decay curves at 1.53 μm and energy transfer mechanism were studied to elucidate 2.7 μm luminescent behaviors. Er 3+ doped NaYF 4 embedded aluminosilicate glass ceramic might provide a new choice for mid-infrared laser and amplifier.
