| 1 |  | 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 |
| 2 |  | Vardeny, Zeev Valentine | Laser action in polydialkylfluorene films: influence of low-temperature thermal treatment | We have used a variety of optical probes to investigate the changes occurring upon low-temperature thermal treatment to the emissive properties of dialkyl substituted polyfluorene thin films. We found that the low-temperature-driven morphological changes involving aggregates formation, which are ob... | Laser action; Polydialkylfluorene films; pi-conjugated polymers; Thermal treatment | 1999 |
