| 中文摘要 | the authors report a random lasing emission from 4-(dicy-anomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4h-pyran doped polystyrene thin films by introducing polystyrene nanoparticles. the aspects of concentration and diameter of polystyrene nanoparticles have been intensively investigated and found that the lasing occurs due to the scattering role of polystyrene nanoparticles. the devices emit a resonance multimode peak centered at a wavelength of 630 nm with a mode linewidth of less than 0.35 nm and exhibit threshold excitation intensity of as low as 0.06 mj pulse(-1) cm(-2). the microscopic laser cavities formed by multiple scattering have been captured. the demonstration of random laser opens up the possibility of using organic scattering as alternative sources of coherent light emission. |
