Colloidal quantum dot lasers

Young-Shin Park et al.

Summary: Semiconductor nanocrystals, also known as colloidal quantum dots, offer promising properties for optical-gain media that can be manipulated via colloidal techniques. Recent advances in understanding and controlling light amplification processes have led to breakthroughs in optically pumped continuous-wave lasing and development of novel dual-function electroluminescent devices that also function as optically pumped lasers. This review evaluates the state of colloidal quantum dot lasing and discusses challenges and opportunities in the field.

Dynamic Formation of Metal-Based Traps in Photoexcited Colloidal Quantum Dots and Their Relevance for Photoluminescence

Indy du Fosse et al.

Summary: Trap states are crucial in colloidal quantum dot technologies, with metal-based trap nature remaining elusive. Photoexcitation can lead to the formation of metal-based traps in charge-neutral CdSe QDs, which are transient and can quench photoluminescence. This highlights the importance of surface redox reactions for the optical properties of QDs and the potential for photoexcitation to create transient in-gap states through atomic rearrangements on the surface.

Raman and Infrared Studies of CdSe/CdS Core/Shell Nanoplatelets

Alexander Lebedev et al.

Summary: The vibrational spectroscopy of semiconductor nanostructures can provide important information regarding their structure. In this study, experimental and calculated vibrational spectra of CdSe/CdS core/shell nanoplatelets were compared, revealing the phonon behavior and surface atomic vibration relaxation in nanostructures. The results indicate a noticeable surface relaxation of the outer Cd layer in the nanostructure, affecting the thickness dependence of certain modes.

Highly versatile near-infrared emitters based on an atomically defined HgS interlayer embedded into a CdSe/CdS quantum dot

Vladimir Sayevich et al.

Summary: This study presents high-quality near-infrared emitters based on CdSe/CdS heterostructures, which are converted from normally visible emitters to highly efficient near-infrared fluorophores by incorporating an HgS interlayer. The structures synthesized in this study exhibit highly efficient photoluminescence with atomic-level precision in defining the thickness of the HgS interlayer, resulting in 'quantized' jumps of the photoluminescence spectrum. Furthermore, the emission from these colloidal quantum dots is virtually blinking free and shows nearly perfect single-photon purity, making them promising for various applications.
