Near Infrared Emitting Quantum Dots: Synthesis, Luminescent Properties and Applications

Abstract

Near-infrared (NIR) luminescent quantum dots (QDs) have been studied very intensively. These QDs have excellent optical properties. Their emitting wavelength can be adjusted by their size and composition, and falls in the telecommunications window, making these QDs promising materials for telecommunication. NIR lights have small background interference and large penetration depth, which make NIR QDs advantageous in bio-imaging applications. This paper reviews the synthesis and optical properties of several representative NIR QDs, including traditional cadmium, mercury, lead and silver, indium based QDs, as well as I-III-IV ternary QDs. Typical applications with NIR QDs luminescence properties, such as light-emitting diodes (LEDs), biology, luminescent solar concentrators (LSCs), doped glasses/fibers, and optical sensing, are also discussed.
