Abstract
AbstractSolution‐processed quantum dot‐based near and short‐wave infrared light emitters have witnessed substantial developments in recent years. A variety of colloidal quantum dots (CQDs)‐based light emitters, including light‐emitting diodes, optical down‐converters, and emitters showing amplified spontaneous emission, lasing in the near and short‐wave infrared region, are demonstrated over the years. The progress in chemical synthesis of CQDs, development of novel CQDs, better understanding of the surface properties, chemical treatments to improve the optoelectronic properties, and suitable device engineering led to tremendous advances in the light emission performance in the near and short‐wave infrared region. A broad investigation is done into various CQD materials to achieve efficient near‐infrared light emitters. This review gives a detailed account of the advancement of the CQD‐based near and short‐wave infrared light emitters, strategies to improve the optoelectronic performance, controlling optical properties, demonstrated applications, the challenges that need to be tackled for further development, and future research direction.
