| 中文摘要: |
| 一直以来光谱学在各类研究中得到了广泛的应用。不同的电磁光谱已被用于各种应用中,导致了各种光谱技术的演变。200 nm(更准确地说是185 nm)波长的光谱却仍旧是一个让光谱学家们警惕的问题。讨论和分析了为什么200 nm以下和以上的光谱技术不同的原因,并进行了相应的分析。最后提出了有效地改进方法,不仅与空气吸收有关,而且与样品的本身属性有着密切的关联。 |

| Spectroscopy has been used in tremendous applications and researches since a long time. Different portions of electromagnetic spectrum have been utilized for this purpose which resulted in evolvement of various spectroscopic techniques. 200 nm (more precisely 185 nm) is still a displeasing hitch which reminds spectroscopists to be cautious while working in the region below 200 nm. In this review,we give reasons and analyze them as well on why are spectroscopic techniques different below and above 200 nm. We also present the short evolution of the techniques how did they develop and the contribution of the scientists.It's not only absorption by air which hinders but it's about the materials useable in this regime and generation and detection together state of the sample. |
