Transient absorption spectroscopy, in addition to its application in studying molecular systems, is a critical technical method for exploring the excited state dynamics of semiconductor nanocrystals or quantum dots. In this discussion, we will use semiconductor quantum dots as an example to elucidat
In the previous article, we thoroughly examined the basic process and detailed principles of transient absorption spectroscopy detection. In this article, we will further explore the application of ultrafast transient absorption spectroscopy in molecular systems, focusing on both ultrafast transient
This article explores the application of laser flash photolysis (LFP) in the field of free radical-mediated pollutant degradation and water pollution control. It begins with an overview of the structure and operation mode of the LFP instrument, followed by a detailed discussion of free radicals closely related to environmental chemistry, including hydroxyl radicals (HO•), sulfate radicals (SO₄•⁻), and reactive chlorine species (RCS). The generation and detection methods of these radicals are examined, with analysis of their formation and detection in LFP systems. The goal is to provide a deeper understanding of LFP techniques and promote their broader application in environmental research.
Basic procedures of transient absorption spectroscopy and its underlying principles.
