Semiconductor nanoparticles, or quantum dots (QDs) were first reported approximately thirty years ago. At that time it was difficult to foresee that they would provide the basis for what has become an important cross-disciplinary research area with far reaching impact in energy production and storage, efficient electronic devices, medical diagnostics, among others. To date, the most widely studied QDs are based upon CdSe; the size dependent properties of these materials are largely understood. Despite the obvious societal benefits afforded by their exquisitely tuneable properties and practical applications, the cytotoxicity of cadmium cannot be ignored and governments are moving to restrict their use.

大约三十年前首次报道了半导体纳米颗粒或量子点 (QD)。 当时很难预见它们将为一个重要的跨学科研究领域提供基础，并对能源生产和存储、高效电子设备、医疗诊断等产生深远影响。迄今为止，研究最广泛的量子点是基于 CdSe 的。这些材料的尺寸依赖性特性已被广泛了解。尽管其精致的可调特性和实际应用带来了明显的社会效益，但镉的细胞毒性不容忽视，各国政府正在采取行动限制其使用。
