摘　　要：利用消光式椭圆偏振光谱法 ,在室温下可见光区对光电子材料镓铟磷的光学参数进行了测量 ,得到该材料的折射率和吸收系数随光子能量的变化关系曲线 ,并对结果进行了分析和讨论 。Optical parameters of GaInP were measured by using null ellipsometric spectrum method in the visible light region at room temperature The dependencies of refractive index and absorption coefficient for three samples on the energy of photons were obtained, and the result was analyzed and discussed The positions of energy gap of three samples were given
