摘　　要：报道了采用多孔硅多层膜作为Bragg反射镜的有机半导体光学微腔 .被测样品的光致发光谱半高宽可由无微腔下的 83nm窄化为有微腔时的 4nm ,非共振模得到有效的抑制 .同时共振峰强度的增强和峰位随出射角增大的“蓝移”The construction of an organic microcavity with an organic light\|emitting thin film sandwiched between a porous silicon Bragg reflector and a silver film is demonstrated.The peak widths of the PL spectra are greatly reduced from 83?nm to 4?nm as compared with those measured from non\|cavity structures.The off\|resonant optical modes are highly depressed.As is always observed from an optical microcavity,the peak intensity is enhanced,and the peak position shows a blue shift with increasing exit angles.
