Effect of X-ray irradiation on CdS1−xSex quantum dots optical absorption

Induced absorption in X-ray-irradiated CdS- and CdSSe-doped glasses

“…We observed increase in absorption. This is different from that reported by Gomonnai et al [2]. Here, we report optical transmission spectra of X-ray irradiated CdS-doped glasses, CdSSe-doped glasses and undoped glass in order to examine the origin of the difference.…”

“…Grabovskis et al [1] reported that the induced absorption was observed in the X-ray-irradiated CdS-doped glasses. On the other hand, Gomonnai et al [2] reported decrease in absorption near absorption edge in CdSSe-doped glass. In a previous article, we reported optical transmission spectra of X-ray irradiated CdS-doped glass [3].…”

Optical Absorption Processes in CdSe Nanocrystals Embedded in Silicate Glass and Organic Polymer Matrices Under 7-MeV Electron Irradiation

“…However, such studies have been reported for X-ray irradiated CdS nanocrystals in silicate glass 47 48 as well as glass-embedded CdS 1−x Se x quantum dots irradiated with both X-rays 49 and high-energy electrons 50 where irradiation-induced transformations of the absorption spectra were explained by the nanocrystal ionization. Therefore, it would be interesting to see whether such effect occurs also for CdSe and, moreover, how this effect depends on the type of the dielectric matrix hosting the CdSe nanocrystals.…”

Effect of X‐ray irradiation on the blinking of single silicon nanocrystals

“…Consequently, the results suggest that the damages induced by X‐rays do not affect the recombination mechanism responsible for the light emission of Si‐NCs. Moreover, in terms of radiation hardness, they seem to perform fairly well, also when compared with Cd‐based alternatives, which are usually exposed to lower doses (4 kGy) and exhibit strong quenching already at those values .…”
