 | Vardeny, Zeev Valentine | Amplified spontaneous emission and lasing in conducting polymers and fluorescent dyes in opals as photonic crystals | Spectral narrowing of photoluminescence (PL) and evolution of sharp emission lines upon optical excitation have been observed in opals made of SiO2 spheres infiltrated with conducting polymers such as OOPPV and MDDOPPV and also fluorescent dyes such as rhodamine 6G, NK-3483, and coumarin 120. Their ... | Amplified spontaneous emission; Lasing; Fluorescent dyes | 1999 |

 | Vardeny, Zeev Valentine; Gellermann, Werner | Laser properties of luminescent conducting polymers in open resonators | We have investigated the lasing properties of several luminescent conducting polymers, i.e. DOO-PPV and the bi-substituted polyacetylenes PDPA-nBu, and PHJPA, dissolved in various polar and non-polar solvents. PP V polymers emit with high quantum efficiencies in broad emission bands centered in the ... | Lasing; Amplified spontaneous emission; Spectral narrowing | 1997 |

 | Vardeny, Zeev Valentine | Lasing and stimulated emission in ∏-conjugated polymers | Recent studies of lasing and stimulated emission in luminescent -conjugated polymers performed by our group are presented. Optical properties of cylindrical high- polymer microcavities are discussed. The emission spectra of plastic microring and microdisk lasers are measured and analyzed. Light-emi... | Lasing; Stimulated emission; pi-conjugated polymers; Microcavities; Polymer lasers | 2000-01 |
