Mechanisms of reversible photodegradation in disperse orange 11 dye doped in PMMA polymer.
An energy level diagram is constructed that describes all measured quantities in the decay and recovery processes and a hypothesis of the nature of the associated states is proposed.
A self healing model based on polymer-mediated chromophore correlations.
A model of self healing in which correlations between chromophores, as mediated by the polymer, are key to the recovery process is presented, and the size distribution of the correlation volume is determined using a grand canonical ensemble through a free energy advantage parameter.
Experimental tests of a new correlated chromophore domain model of self-healing in a dye-doped polymer
Temperature-dependent photodegradation and recovery studies of Dipserse Orange 11 (DO11) dye dissolved in poly(methyl methacrylate) and polystyrene polymer hosts are used as a test of a new model
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse Orange 11 doped in poly(methyl methacrylate)
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in poly(methyl methacrylate) is not due to dye diffusion—a common phenomenon observed in many dye-doped polymers.
Imaging studies of photodamage and self-healing in disperse orange 11 dye-doped PMMA
We report on optical imaging studies of self-healing after laser-induced photodamage in disperse orange 11 dye doped into poly(methyl methacrylate) (PMMA) polymer. In particular, the high
The role of the polymer host on reversible photodegradation in Disperse Orange 11 dye
The photodegradation and recovery process in anthraquinone chromophores have been characterized using am plified spontaneous emission (ASE) in several Anthraquinone derivatives doped in poly(methyl
Experimental verification of a self-consistent theory of the first-, second-, and third-order (non)linear optical response
We show that a combination of linear absorption spectroscopy, hyper-Rayleigh scattering, and a theoretical analysis using sum rules to reduce the size of the parameter space leads to a prediction of
Recent progress in reversible photodegradation of Disperse Orange 11 when doped in PMMA
We report observations that dye-doped PMMA polymer with the organic dye Disperse Orange 11 exhibits self healing after photodegradation by continuous optical pumping whereas in liquid solution,
