Synthesis and characterization of AgInS2–ZnS heterodimers with tunable photoluminescence

Facile synthesis and photoluminescence characterization of AgInZnS hollow nanoparticles

“…It could be observed the emission wavelength was located at 650 nm with a full width at half-maximum (FWHM) around 120 nm which is significantly broader than the high quality CdSe but similar to the CuInS 2 based QDs [25,26]. From the element ratio of the Ag: In: Zn (1: 0.98: 1.67), which is constant with the reported results of AgInZnS alloyed nanopartilces [22,23]. Furthermore, because the matching lattice parameters of alloy AgInS 2 and ZnS, this could reduce the formation of structural defects when formed as AgInZnS alloy, which could further lead to the blue shift of band gap after zinc doped.…”

“…In the past years, several approaches have been employed to prepare I-III-VI 2 nanocrystals including solvothermal methods, decomposition of single-source methods, and hot injection techniques [18,21,22]. Hot injection method had been successfully used for synthesis of CuInS-ZnS and AgInS-ZnS alloy nanoparticles with bright and tunable photoluminescence in our former research [23,24].…”

Encapsulation of lanthanides in ternary I–III–VI AgInS2 nanocrystals and their physical properties

“…In addition, they avoid the encapsulation of toxic elements like cadmium or selenium. Compared with conventional quantum dots (CdTe or Si), they exhibited considerably enhanced photostabilities under long-term excitations [6][7][8]. Very recently, the new alloys with well-structured metals (commonly as ZnS) have received considerable interest due to the improvement of the quantum yields.…”

Synthesis and temporal evolution of Zn-doped AgInS2 quantum dots

“…For example, AIS nanoparticles prepared in a hot organic solution exhibited intense photoluminescence with a broad peak ascribed to donor-acceptor pair recombination. The emission peak and the quantum yield were tunable by coated with a wider band-gap semiconductor such as ZnS [10,11]. Up to now, much efforts have been invested to synthesis coreeshell nanocrystals in order to minimize the structural defects, making the crystal structure more stable to improve the quantum yield, thus to obtain high quality semiconductor nanocrystals [12,13].…”
