摘要	We report random lasing achieved in a MEH-PPV/glass waveguide with the TiO2 scatterers in diameter 20 nm that is significantly smaller than submicrometre of TiO2 scatterers in the films or suspensions previously reported on random lasing. The spectral lines are dramatically narrowed by almost two orders of magnitude compared with those excited by a xenon lamp. The amplified spontaneous emission is identified as the dominant mechanism in our system. Light localization might be achieved in a broad class of random materials based on the features of the mean free path l* = 5.4 x 10(5) nm, kl* much greater than 1 and the Thouless number 6.73 x 10(-5) with k being the wave number.
