A microscope observing the photoluminescence excited by an argon ion laser was produced for the research on the photo-induced structural change in amorphous semiconductors. The end of the optical fiber with 0.3 mm diameter was fixed on the position making the image in the microscope with x-y stages. The stages were driven with the strpping motors controlled by a personal computer. The photoluminescence guided into the optical fiber was detected with a photomultiplier and counted with a photon counter. The data were processed with the personal computer.The distribution of the photoluminescence intensity in Hoya 0-56 glass including microcrystals of the concentration of 1 % was observed. The photoluminescence is obtained by exciting mictocrystals. It was founsd in this observation that the area emitting the photoluminescence was larger by 50 <micro>m than the area excited by the argon ion laser. This is considered to be due to the energy transfer of the excited state ot microcrystals or the self-absorption by the microcrystals.

生成了通过氩离子激光激发的光致发光的显微镜，以研究无定形半导体的光诱导的结构变化。直径为0.3毫米的光纤的末端固定在位置上，使图像在显微镜中具有X-Y阶段。这些阶段是由由个人计算机控制的踩踏电动机驱动的。用光电层次检测到光纤进入光纤的光发光，并用光子计数器进行计数。使用个人计算机处理数据。观察到Hoya 0-56玻璃中的光致发光强度的分布，包括1％浓度的微晶。光致发光是通过令人兴奋的小晶体获得的。在这一观察结果中，发射光致发光的区域比氩离子激光激发的区域大于50 <micro> m。这被认为是由于激发态微晶的能量转移或微晶的自我吸收。
