Nanocrystals, also known as quantum dots, are semiconducting particles with a diameter of a few millionths of a millimeter.

纳米晶体，也被称为量子点，是一种直径只有百万分之一毫米的半导体粒子。

The researchers began by making samples of one or two monolayers of PbSe quantum dots deposited on flat single-crystalline TiO2.

研究人员首先在单晶体 TiO2 平面上制作一层或两层的单分子硒化铅量子点。

Quantum dots may leap to the rescue.

量子点可能填补其它技术缺陷的空白。

Quantum dots are still a technology in their infancy.

量子点仍是一种未成熟的技术。

Most attention has been paid to quantum dots (QDs).

其中研究最多的是半导体量子点。
