采用脉冲激光辅助的液体环境方法成功合成了可调尺寸（5 ~ 12nm）和不同形状（球形、棒状、绳状）的纳米II-VI半导体（硫化镉）。这种方法可以通过两种方式实现；第一种是自顶向下的技术，在过去的几十年里已经在出版物中讨论过，另一种是自底向上的技术，在本文中首次出现。x射线衍射、紫外可见光谱学和透射电子显微镜证实纳米颗粒是结晶性的。这些方法导致纳米材料的生产，这对光子学和生物传感应用很重要。这两种合成方法都可以应用于所有材料，因为它们具有超高的能量密度，可以烧蚀几乎所有类型的材料，并且可以通过操纵强度、波长等工艺参数来控制生长过程。
A pulsed laser-assisted in liquid environment method has been developed successfully to synthesize size-tunable (5-12nm) and different shapes (sphere, rod, rope) of nano II-VI semiconductor (cadmium sulfide). This method can be carried out in two ways; the first one is the top-down technique, which has been discussed in publications in the last few decades, and the other one is the bottom-up technique, which appears for the first time in this paper. X-ray diffraction, ultraviolet-visible spectroscopy, and transmission electron microscopy confirm that the nanoparticles are crystalline. The methods lead to the production of nanomaterials, which are important for photonics and biosensing applications. Both synthesized methods can be applied in all materials because of their ability to ablate almost all kinds of materials due to the ultrahigh energy density and control over the growth process by manipulating the process parameters such as intensity, wavelength, and so on.
