Abstract
This paper reports the preparation and characterization of LaF3-based glass–ceramic (GC) optical fibers codoped with Er3+ and Yb3+ ions, using the rod-in-tube method with Duran glass as cladding. Structural analysis, including x-ray diffraction and transmission electron microscopy, confirmed the presence of LaF3 nanocrystals in the core, with sizes ranging from 8 to 10 nm, slightly smaller than those observed in bulk samples due to the higher cooling rate during fiber drawing. Optical measurements showed transmission losses of 13 dB/m for the GC fibers after heat treatment at 660°C for 40 h. Upconversion (UC) emissions were observed in the green (2H11/2, 4S3/2 → 4I15/2), red (4F9/2 → 4I15/2), and blue (2H9/2 → 4I15/2) regions upon excitation at 980 nm. The dependence of UC emission on pump power showed a near linear dependence, which can be explained by saturation effects in the intermediate energy states and indicates that the UC process is driven by energy transfer from Yb3+ to Er3+ ions. These results demonstrate the potential of these fibers for advanced optical applications, including telecommunication, sensors and laser technologies.
