應用

我们的硫化铅 (PbS) 量子点 (QD) 的尺寸在2.5到8 nm之间变化,并且因此这些QD可发出的波长介于900-1600 nm之间。我们的PbS量子点具有高量子产率、清晰的发射和窄的荧光带(半峰全宽<100 nm),这使其适合用作太阳能电池、光电探测器和红外发光二极管(LED)中的光吸收剂或IR发射器

The detection of photons underpins imaging, spectroscopy, fibre-optic communications and time-gated distance measurements. Nanostructured materials are attractive for detection applications because they can be integrated with conventional silicon electronics and flexible, large-area substrates, and can be processed from the solution

A solution-based passivation scheme is developed featuring the use of molecular iodine and PbS colloidal quantum dots (CQDs). The improved passivation translates into a longer carrier diffusion length in the solid film. This allows thicker solar-cell devices to be built

Quantum Dots for Electronics and Energy Applications

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.
