| 摘 要： | 采用特征矩阵法分别计算奇、偶数层布喇格反射镜的反射相移,利用反射时延与反射相移的关系给出了其穿透深度的表达式.采用电子束热蒸发的方法制备了结构为HL]2H的布喇格反射镜,并制作了有机微腔器件,测量和计算了其透射光谱、反射相移和穿透深度,得到了微腔的有效腔长,测量值与实验值吻合较好,验证了该穿透深度公式的正确性.

| Abstract: | The analytical expressions for the phase shift on reflection of Distributed Bragg Reflectors (DBRs) with odd and even numbers were derived based on the transfer-matrix method.The expression for the penetration depth of DBR as a function of phase shift was given according to the relationship between the phase shift and the reflection delay.The DBR with the structure ofHL]2H was fabricated by electron beam evaporation and the transmittance spectrum,and phase shift and penetration depth were measured or simulated.The microcavity organic light emitting diode (MOLED) was fabricated using the designed DBR.The measured effective cavity length of the MOLED fit well with the calculated one. |
