Definition of photoionization in English:

photoionization

(British photoionisation)

noun ˌfəʊtəʊˌʌɪənʌɪˈzeɪʃ(ə)nˌfoʊdoʊˌaɪənəˈzeɪʃ(ə)n

mass nounPhysics

Ionization produced in a medium by the action of electromagnetic radiation.
〔物理〕光致电离，光化电离
Example sentencesExamples
- T-rays have low photon energies and will not cause harmful photoionization in biological tissues.
- Firstly, there is no charge separation or corresponding Coulomb attraction barrier, because the electron is ejected and hydrated in the bulk directly by photoionization.
- This oxidizing process leads to the formation of a guanine radical cation, similar to that formed by DNA photoionization which may be considered as the main intermediate in DNA oxidation.
- Moreover, this spectrum is strikingly similar to the terminal spectrum measured after photoionization of the isolated PYP chromophore in solution.
- The following interesting features should shed some light on the mechanism of photoionization in duplex DNA.
