提出了一种新的色散元件--量子点阵列衍射光栅[L. F. Cao，中国专利No.200410081499（2004年8月10日）]已经开发并实验表征了用于可见光的光致发光器件。大量的量子点以正弦函数形式分布在基底上，可以用来吸收x射线而不需要高阶衍射。实验结果表明，这种新型元件可以有效地消除传统衍射光栅记录光谱中不可避免的高阶衍射。这表明，量子点阵列衍射光栅是一个有吸引力的替代目前使用的衍射光栅在软x射线光谱应用，以消除高阶衍射失真。
A new dispersive element named as quantum-dot-array diffraction grating [L. F. Cao, China patent No. 200410081499 (August 10, 2004)] for visible light has been developed and characterized experimentally. A large number of quantum dots distributed on a substrate as sinusoidal function can be used to diffract x rays without higher-order diffraction. The experimental patterns show that the higher-order diffractions which inevitably exist in the spectrum recorded using traditional diffraction gratings can be eliminated effectively by this newly designed element. It indicates that quantum-dot-array diffraction grating could be an attractive alternative of presently used diffraction grating in soft x-ray spectroscopy application to get rid of the higher-order diffraction distortions.
