Polylactic acid promotes healing of photodegraded disperse orange 11 molecules

We report on the recovery of a photodegraded organic molecule mediated by a biopolymer. Amplified spontaneous emission (ASE) from disperse orange 11 (DO11) dye-doped polylactic acid (PLA) was used to monitor photodegradation while the material was being damaged by a strong pump laser. The ASE signal...

Description
Summary:We report on the recovery of a photodegraded organic molecule mediated by a biopolymer. Amplified spontaneous emission (ASE) from disperse orange 11 (DO11) dye-doped polylactic acid (PLA) was used to monitor photodegradation while the material was being damaged by a strong pump laser. The ASE signal fully recovers over two hours time when the pump beam is blocked. The fluorescence spectra was also observed to recover after partial photobleaching the dye-doped polymer. PLA is the first biopolymer known to mediate the recovery of a photodegraded organic dye molecule. •Discovered third known polymer matrix to promote healing of a photodegraded organic molecule.•Discovered first known dye-doped biopolymer material that self-heals.•Fast recovery time of the ASE amplitude after photodegradation of the dye.•The ASE was found to recover beyond 100% after partial degradation of disperse orange 11 in the polylactic acid matrix.
