High quantum efficiency luminescence from a conducting polymer in solution: A novel polymer laser dye
Abstract
A novel dye laser based on the soluble conducting polymer poly[2-methoxy, 5-(2' ethyl-hexyloxy)-p-phenylenevinylene], MEH-PPV, has been demonstrated. Laser action has been tested in a transverse cavity configuration where the conducting polymer laser was pumped by light pulses generated from the second harmonic radiation of a Q-switched Nd:YAG laser. The performance of MEH-PPV in solution as a laser dye was compared to that of rhodamine 6G in solution under identical conditions. The results indicate that the quantum yield of MEH-PPV laser is comparable to that of rhodamine 6G.
