Quantum dots with fabulous size-dependent and color-tunable emissions remained as one of the most exciting inventories in nanomaterials for the last 3 decades. Even though a large number of such dot nanocrystals were developed, CdSe still remained as unbeatable and highly trusted lighting nanocrystals. Beyond these, the ternary I–III–VI family of nanocrystals emerged as the most widely accepted greener materials with efficient emissions tunable in visible as well as NIR spectral windows. These bring the high possibility of their implementation as lighting materials acceptable to the community and also to the environment. Keeping these in mind, in this Perspective, the latest developments of ternary I–III–VI nanocrystals from their large-scale synthesis to device applications are presented. Incorporating ZnS, tuning the composition, mixing with other nanocrystals, and doping with Mn ions, light-emitting devices of single color as well as for generating white light emissions are also discussed. In addition, the future prospects of these materials in lighting applications are also proposed.

从大规模合成到照明设备中三元I–III–VI半导体纳米晶体的应用：激发更环保的材料发射器

在过去的30年中，具有惊人的尺寸依赖性和颜色可调发射的量子点仍然是纳米材料中最令人兴奋的清单之一。尽管已经开发了许多这样的点纳米晶体，但CdSe仍然是无与伦比且备受信赖的照明纳米晶体。除这些之外，三元I–III–VI纳米晶体家族已成为最广泛接受的绿色材料，其有效发射在可见光和NIR光谱窗口中均可调。这些带来了将其实施为社区和环境可接受的照明材料的可能性。牢记这些，在此“观点”中，将介绍三元I–III–VI纳米晶体从大规模合成到器件应用的最新进展。掺入ZnS，调整成分，还讨论了将其与其他纳米晶体混合并掺入Mn离子后，该单色发光器件以及用于产生白光发射的技术。此外，还提出了这些材料在照明应用中的未来前景。
