Experimental tests of the correlated chromophore domain model of self-healing in a dye-doped polymer
Shiva K. Ramini, Sheng-Ting Hung, Mark G. Kuzyk
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…
A Self Healing Model Based on Polymer-Mediated Chromophore Correlations
Shiva Kumar Ramini, Mark G. Kuzyk
Here we present a model of self healing in which correlations between chromophores, as mediated by the polymer, are key to the recovery process. Our model determines the size distr…
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse orange 11 doped in PMMA
Shiva K. Ramini, Nathan Dawson, Mark G. Kuzyk
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in PMMA is not due to dye diffusion - a common phenomenon observed in many dye-doped polymers. Th…
Imaging Studies of photodamage and self-healing in disperse orange 11 dye-doped PMMA
Benjamin Anderson, Shiva K. Ramini, Mark G. Kuzyk
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, t…
Experimental verification of a self-consistent theory of the first-, second-, and third-order (non)linear optical response
Mark G. Kuzyk, Javier Perez-Moreno, Juefei Zhou +3
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…
Mechanisms of reversible photodegradation in disperse orange 11 dye doped in PMMA polymer
Natnael B. Embaye, Shiva K. Ramini, Mark G. Kuzyk
We use amplified spontaneous emission (ASE) and linear absorption spectroscopy to study the mechanisms of reversible photodegradation of 1-amino-2-methylanthraquinone (disperse ora…
