nanoparticles possess an intensive near-IRphotoluminescence ranging up to 0.9 eV (ca. 1400 nm). In this article, we explain the reasons for the formation of the ellipsoidal nanoparticles as well as the peculiarities of the process. The structure, Ag content, and optical properties of quantum dots are also
investigated. The optimal conditions for maximizing both the reaction yield and IRphotoluminescence quantum yield are found.

Colloidal quantum dots (QDs) have attracted considerable
solution of the same absorbance at 405 nm. IR-photoluminescence spectra were obtained with a MDR-23 monochromator with Ge photodetector calibrated with a 2600 K W-lamp.
Transmission electron microscopy (TEM) studies were performed using JEOL JEM2100 and Tecnai G2 30 UT (LaB6) microscopes operated at 200
