Research Focus:
Our group investigates the photostability, photoluminescence, and photoconductivity of organic laser dyes in solution and dispersed in a polymer matrix. We aim to understand the mechanism of photodegradation and employ methods to decrease the rate of photodegradation, i.e. add antioxidants to preclude singlet oxygen mediated photooxidation. Since singlet oxygen mediated (Type II photooxidation) is such an important contribution to the photodegradation mechanism of many dyes, we also employ time-resolved sinlget oxygen phosphorescence to measure the singlet oxygen generation quantum yield and quenching rate constant of many laser dyes and antioxidants respectively. Applications of this research include: solid-state dye lasers, energy transfer dye lasers, planar waveguides, organic light emitting devices (OLEDs), read/write disks (DVDs), and solar cells.
