摘要

研究了MEH-PPV薄膜的放大自发发射特性。当激发强度增加时

从样品边缘发射的光谱发生增益窄化现象并具有明显的阈值特性。我们发现随着薄膜厚度的增加

MEH-PPV薄膜的阈值有所降低

而其增益系数则随之增加。在150nm厚时测得最大净增益系数为25.03cm

-1

最低阈值为2.2μJ/pulse。结果表明MEH-PPV是一种优良的激光和光放大材料。

Abstract

Amplified spontaneous emission(ASE) from the structure comprised of a poly(2-methoxy-5-(2′-ethylhexyloxy)-1

4-phenylene vinylene) (MEH-PPV) film deposited on SiO

was reported.The change of the emission spectra detected from the edge of the sample showed a clear threshold and gain narrowing phenomenon when increasing the excitation intensity.With increasing the thickness of the polymer film

the threshold of ASE diminishes and the net gain increases.A maximum net gain of 25.03 cm

-1

and a minimum threshold of 2.2 μJ/pulse are obtained at the thickness of 150 nm.Our results indicate that MEH-PPV is an attractive gain medium in optically pumped polymer lasers and amplifier.
