Preparation and Spectroscopy of Lead-Tin Fluorophosphate Glass Doped with TPPS and TPPS-Sn

摘要

Tetraphenyl-porphine-tetrasulfonic acid (TPPS), which is a well known dye for photochemical hole burning (PHB), and its Sn complex (TPPS-Sn) were incorporated into a low melting SnF_2-P_2O_5-SnO-PbF_2 glass system with a conventional melting method. From the absorption and luminescence spectroscopy, it was found that in the glass the above organic dyes were not decomposed and the original structure of TPPS-Sn was maintained, however the structure of TPPS changed from that in the aqueous solutions. The excitation spectra and the extraction of the dyes suggest that TPPS reacted with Sn during melting, and TPPS-Sn. TPPS and/or TPPS-Sn with one pyrrole reduced were produced. This is supported by the result of PHB measurement.
