Facile synthesis of CdZnS QDs: Effects of different capping agents on the photoluminescence properties

Environmentally friendly approach to the synthesis of monodisperse and bright blue emitting Cd0.15Zn0.85S quantum dots

“…The mean crystalline size of Cd0.15Zn0.85S nanocrystals is in the range of 3 -4 nm. Thus, the obtained results for all prepared QDs are in a good agreement with previously published results [22,24]. As described above, Cd0.15Zn0.85S QDs prepared with (Z)-N-(octadec-9-enyl)-N′phenylthiourea formed a single phase with cubic zinc blende structure with the space group F-43m (Figure 3c).…”

The systematic study of the precursor ratio effect in the Cd–Zn–S quantum dot synthesis

“…The presence of three components in the PL decay kinetics of ternary QDs has been observed by many authors [22,44,50,51]. The presence of several temporal components of the PL decay curves is associated with the existence of different carrier recombination paths in these QDs [50].…”

“…A protective shell consisting of one or more ligands plays an important role both in the formation of the nanocrystal and in the determination of the chemical and physical properties of the final product [21]. The main purpose of the protective shell is to prevent the agglomeration of QDs, and to transfer the QDs to an organic or inorganic medium in the form of a sol [22]. Currently, the most effective agents for the formation of a protective shell are fatty carboxylic acids [23].…”

Cu-Enhanced Efficient Förster Resonance Energy Transfer in PBSA Sunscreen-Associated Ternary CuxCd1–xS Quantum Dots

“…8,9,16 More recently, Cu-based II−VI semiconductor nanocrystals such as Cu x Cd 1−x S (CCS) have emerged as promising candidates due to their specific advantages relative to their corresponding binary counterparts CuS and CdS, which allow tuning the desirable optoelectronic properties. 17 In addition, Cu chalcogenide QDs are inexpensive, stabilized under photoirradiation, moisture and oxygen, biocompatible, and durable. 18−20 In parallel in the past two decades, there has been growing interest to prepare the biocompatible semiconductor QDs containing sunscreen systems to filter the ultraviolet (UV) radiations.…”
