Lasing from a planar waveguide with the blend of Polystyrene(PS): Poly-methylmethacrylate(PMMA) doped with tris(8 -hydroxyquinolinato)aluminum(Alq3) and 4-(dicyanomethylene)-2-tertbutyl- 6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran(DCJTB) was investigated.Due to phase separation of the blend of PS:PMMA during the solvent evaporation process,a waveguide with granular surface was obtained,which has 2D island-like nanostructures with diameters ranging between 200 and 400 nm and heights at about 25 nm.
