采用有机分子束沉积技术生长了由8-羟基喹啉铝（Alq 3）和芳香族二胺（TPD）交替层组成的多量子阱结构。通过X射线衍射、光吸收和光致发光确定了多量子阱结构。Alq 3的光致发光峰随着层厚度的减小而向更高的能量移动，这表明量子尺寸效应。用Alq 3/TPD多量子阱结构制作了电致发光二极管。
Multiple quantum well structure consisting of alternating layers of organic 8‐hydroxyquinoline aluminum (Alq3) and aromatic diamine (TPD) has been grown by organic molecular beam deposition. The multiple quantum well structure was determined by x‐ray diffraction, optical absorption, and photoluminescence. Photoluminescence peak of Alq3 shifts to higher energy with decreasing layer thickness, suggesting a quantum size effect. An electroluminescent diode has also been fabricated by using Alq3/TPD multiple quantum well structure.
