Attention is recently paid to the new materials for tunable laser diode, lasing at about 3.5mum. The laser diodes are expected as the light source for optical communications in the next generation. The quarternary (Pb_<1-x>Cd_x) (S_<1-z>Se_z)_<1+y> are best suited to the above purposes. In this study, a new method for simultaneously controlling the composition x,z and the deviation y from stoichiometry was proposed for the quarternay solid solution. That is, the activity of sulfur(Ps_2), selenium(Pse_2) and CdS_<1-z>Se_z(a_<cds1-z'sez'>) were controlled independently in the heat-treatment process of the solid solution by providing two reservoir chambers in the heat-treatment tube. They are the mixing reservoir of sulfur and selenium and a CdS reservoir. As a result, it was found that the composition x and z of the solid solution is seriously effected by a CdS reservoir(a_<cds1-z'sez'>) and the mole ratio of S and Se in the mixing reservoir, respectively. The deviation y from stoichiometry could also be controlled simultaneously by regulating the sum of chalcogen partial pressures (Ps_2+Pse_2), keeping a_<cds1-z'sez'> and the mole ratio of sulfur and selenium in the mixing reservoir to a specific value corresponding to the target composition x and z. Based on this principle, the diagrams of P(Ps_2+pse_2)-T(heat-treatment temperature)-y(deviation from stoichiometry) was obtained successfully for this quarternary solid solution.

最近注意可调激光二极管的新材料，激光约为3.5mum。预计激光二极管是下一代光学通信的光源。季度（pb_ <1-x> cd_x）（s_ <1-z> se_z）_ <1+y>最适合上述目的。在这项研究中，提出了一种用于控制组成X，Z和化学计量的偏差y的新方法，以用于季度实心溶液。也就是说，硫（PS_2），硒（PSE_2）和CDS_ <1-Z> se_z（A_ <cds1-Z'sez'>）的活性在固体溶液的热处理过程中独立控制，通过在热处理管中提供两个储层室，通过提供两个储层。它们是硫和硒的混合储层以及CDS储层。结果，发现固体溶液的组成X和z分别受CDS储层（A_ <cds1-Z'sez'>）和S和SE在混合储层中的摩尔比分别严重影响。通过调节chalcogen部分压力（PS_2+PSE_2）的总和，可以同时控制与化学计量的偏差，并保持A_ <cds1-Z'sez'>以及硫和硒的摩尔比率与混合物中的硫和硒的摩尔比相对应与特定的值相对应与特定的值相对应的靶标组合x和z。基于此原理，对于此季度实心溶液，成功获得了P（PS_2+PSE_2）-t（热处理温度）-y（偏离石化计量）的图（偏离石化计量）。
