[资源] Nature子刊最新综述：胶体量子点发光技术的出现

最新一期的Nature Photonics杂志（自然·光子学）刊发了由量子点大牛M.G. Bawendi和V. Bulović课题组撰写的关于胶体量子点发光技术的综述文章，题目为Emergence of colloidal quantum-dot light-emitting technologies。以锌、镉的硫属化合物为代表的量子点在光致发光以及电致发光领域一直收到广泛的研究，本文介绍了锌、镉的硫属化合物等胶体量子点的发光原理已经研究进展。文章11页，引文158篇。
Since their inception 18 years ago, electrically driven colloidal quantum-dot light-emitting devices (QD-LEDs) have increased in external quantum efficiency from less than 0.01% to around 18%. The high luminescence efficiency and uniquely size-tunable colour of solution-processable semiconducting colloidal QDs highlight the potential of QD-LEDs for use in energy-efficient, high-colour-quality thin-film display and solid-state lighting applications. Indeed, last year saw the first demonstrations of electrically driven full-colour QD-LED displays, which foreshadow QD technologies that will transcend the optically excited QD-enhanced lighting products already available today. We here discuss the key advantages of using QDs as luminophores in LEDs and outline the operating mechanisms of four types of QD-LED. State-of-the-art visible-wavelength LEDs and the promise of near-infrared and heavy-metal-free devices are also highlighted. As QD-LED efficiencies approach those of molecular organic LEDs, we identify the key scientific and technological challenges facing QD-LED commercialization and offer our outlook for on-going strategies to overcome these challenges.
