Paper Abstract

The use of a Tris-(8-hydroxyquinoline) Aluminum (Alq3) organic active region within a distributed Bragg reflector (DBR) mirror-cavity structure is described. The resultant device showed a narrowing of spectral output with increasing DBR usage significantly purifying the broadband emission of Alq3. Higher excitation intensities resulted in the production of lasing with a threshold of 3.2 kW/cm2.
