Enhanced Ultraviolet Photoluminescence of Gd in Silica Glass
نویسندگان
چکیده
Enhancement of photoluminescence (PL) signal from Gd-doped silica glass densified by rapid thermal treatment (RTT) in the ultraviolet (UV) is investigated. Significant decrease of the loss covering the UV band is observed. The strong emission detected at 314 nm is assigned to the P7/2 to S7/2 transition under excitation of DJ, IJ, and PJ energy levels of the Gd.

We report the fabrication and characterization of a photonic crystal fiber (PCF) having a sol-gel core doped with ionic copper. Optical measurements demonstrate that the ionic copper is preserved in the silica glass all along the preparation steps up to fiber drawing. The photoluminescence results clearly show that such an ionic copper-doped fiber constitutes a potential candidate for UV-C (200...
