摘要:

我们证明了一个大的光吸收率(80%)的纳米层的量子点在杆(QR)的厚度为23 nm。这种行为是解释的相干吸收的光入射在一个特定的角度到非常薄的QR层的干涉。我们利用这种相干光吸收来增强来自QR的光致发光发射。高达七倍和五倍的增强的光致发光观察p-和s-偏振入射光,分别。

英文摘要:

We demonstrate a large light absorptance (80%) in a nanometric layer of quantum dots in rods (QRs) with a thickness of 23 nm. This behavior is explained in terms of the coherent absorption by interference of the light incident at a certain angle onto the very thin QR layer. We exploit this coherent light absorption to enhance the photoluminescent emission from the QRs. Up to a seven- and fivefold enhancement of the photoluminescence is observed for p- and s-polarized incident light, respectively.
