“…Figure 4 a shows the absorption spectra of AgInS 2 QDs at different amounts of PVP. A broad and featureless absorption curve with a long absorption tail in the low-energy area without clearly defined excitonic maxima were observed for all samples [ 26 , 27 ]. The variation of the PVP concentration did not affect either the form or the position of the absorption band.…”

“…The PL measurement results presented in Figure 4 b are in good agreement with similar works where these types of QDs were stabilized using L-glutathione [ 28 ] or mercaptopropionic acid [ 29 ]. The variation of the molar ratio between metals of groups I and III in I–III–VI QDs led to a change in the energy gap and the PL peak position [ 26 , 27 ]. The decrease in the molar ratio [Ag]:[In] may lead to a change of the predominant defect-related luminescent channel as well as to a widening of the band gap.…”

“…В таких технологических режимах возможно получение гидрофильных НК без дополнительных операций по обработке гидрофобной поверхности. Кроме того, такой подход является более экологичным и менее затратным [3,4].…”

“…2 показана зависимость максимума ФЛ для НК AgInS 2 и AgInS 2 /ZnS от дозы облучения. Для ФЛ как НК AgInS 2 , так и AgInS 2 /ZnS характерен широкий спектр излучения с двумя типичными максимумами (около 650 и 720 nm) [3]. Большое значение полуширины спектров фотолюминесценции НК системы I−III−VI и проявление нескольких полос испускания являются характерной особенностью этого класса частиц [1,2].…”
