Elaboration and Mid-infrared Emission of KYb3F10∶Er3+ Nanocrystals Embedded in Glass Ceramics增强出版
Mid-infrared lasers operating at around 3 μm have been paid much attention due to their significant potential at civil and military field. Traditional mid-infrared laser glass matrix presents high phonon energy, which causes the radiative transition probability of luminescent ions being greatly weakened, and thus leads to the inability to obtain effective laser output. Therefore, it is of great value to explore efficient and stable gain materials for 3 μm laser. In this paper, we report the ,in-situ, precipitation of KYb,3,F,10,∶Er,3+, nanocrystals from SiO,2,-ZnF,2,-KF-YbF,3,-ErF,3, fluorosilicate glass matrix. The obtained glass ceramic can maintain more than 80% transmittance. The nanocrystal species and elemental distribution in the glass were characterized by X-ray diffractometry(XRD) and transmission electron microscopy(TEM) technology. Under 980 nm laser diode(LD) excitation, the mid-infrared emission at 2.7 μm of Er,3+,for the heat-treated sample is greatly enhanced, which is about 19 times stronger than that of the precursor sample. The related mechanism for the luminescence enhancement is further explained by the results of absorption spectra and steady state fluorescence spectra. The present results may provide reference data and research ideas for the development of ~3 μm laser gain materials.
