Semiconductor nanoparticles (NPs) are now contributing to major advances in solar cell and display technologies, biological and medical imaging and nanophotonics. While these photoactive materials offer high, light harvesting and photoluminescence (PL) efficiencies, their performance is limited by a number of photo-instabilities that ultimately affect both photon absorption and emission yields, as well as their working lifetime in applications. The Osborne Lab conducts research into the mechanism and control of optical properties in nanoparticles, from classical CdSe quantum dots (QDs) to new perovskite (CsMX3, M=Pb, Sn, X=Cl, Br, I) QDs and nanowires (NWs) and now offers PhD research in this productive area.[1-4]

半导体纳米粒子(NPs)目前正在为太阳能电池和显示技术、生物和医学成像以及纳米光子学的重大进步做出贡献。虽然这些光活性材料提供了高的光捕获和光致发光(PL)效率，但它们的性能受到许多光不稳定性的限制，这些光不稳定性最终会影响光子吸收和发射效率，以及它们在应用中的工作寿命。奥斯本实验室对纳米粒子的光学性质的机理和控制进行了研究，从经典的CdSe量子点(Qds)到新的钙钛矿型(CsMX3，M=Pb，Sn3，X=Cl，Br1，I)量子点和纳米线(NWS)，目前在这一生产领域提供博士研究。
