ABSTRACT:- Semiconducting quantum dots, whose particle size is in the nanometer range, have very unusual properties. The quantum dots have band gaps that depend in complicated ways on a number of factors described in the article. The relationships between processing, structure, properties, and performance are examined for semiconducting quantum dots. Various methods for synthesizing these quantum dots and the resulting properties are discussed. Quantum states and confinement of their excitons can shift their optical absorption and emission energies. Such effects are important for tuning their luminescence, which is excited by photons (photoluminescence) or an electric field (electroluminescence). In this article, the decoupling of quantum effects in excitation and emission is described, as well as the use of quantum dots as sensitizers in luminescent materials. In addition, multimodal applications of quantum dots are discussed, including electroluminescent devices, solar cells, and biological imaging.

KEYWORDS:- Quantum dots, Semiconducting nanomaterials, Electroluminescence, Photoluminescence, biological imaging.
