One of the limiting factors of optical devices for space applications is photodamage from high intensity light and radiation. Dye doped polymers offer many advantages in device design but are susceptible to photodamage, especially due to high intensity UV radiation. Several organic dyes have been observed to self heal after photodegradation. We seek to understand the underlying mechanism with the goal of designing materials that are more robust to photodegradation. We test the hypothesis that…

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,
Mechanisms of reversible photodegradation in disperse orange 11 dye doped in PMMA polymer.
TLDR
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.
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
Amplified spontaneous emission and recoverable photodegradation in polymer doped with Disperse Orange 11
We report optically pumped lasing action at the attractive wavelength of 650 nm in the common organic dye 1-amino-2-methylanthraquinone (Disperse Orange 11). The dye was incorporated into poly(methyl
Lasing action and photodegradation of Disperse Orange 11 dye in liquid solution
We report optically pumped lasing action near 650nm of 1-amino-2-methylanthraquinone (known as Disperse Orange 11 or DO11) in the common laser dye solvents dimethylformamide and dimethylsulfoxide.
Matrix and donor/acceptor dependence of polymer dispersed pyrromethene dye photoconductivity
Transient photocurrent measurements were peTformed on pyrromethene dyes dispersed in polymer matrices to investigate the feasibility qf these materials as the basis@ novel optoelectronic devices. The
Two-photon fluorescence measurements of reversible photodegradation in a dye-doped polymer.
TLDR
The energy dependence suggests that photodegradation is a linear process, while recovery is entropic, which could be useful to high-intensity devices such as two-photon absorbers, which can be used in many applications.
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.
Fluorescence decay and recovery in organic dye-doped polymer optical fibers
Photostabilities of several dye-doped polymer optical fibers are investigated experimentally. In the spectral fluorescence of those fibers doped with dyes such as fluorescein and pyrromethene, a
High Photoresponsivity of Pentacene-Based Organic Thin-Film Transistors with UV-Treated PMMA Dielectrics
A simple UV-treatment process for polymethyl methacrylatePMMA dielectric is proposed to enhance photoresponsivity of pentacene-based organic thin-film transistors. The UV treatment creates excess
