Very few near-infrared light emitters exist, and these have very low emission quantum yields and also low brightness. There are some quantum dots that emit near-infrared light, but most of these are composed of toxic elements. There is a need for bright light emitters that are not toxic and emit in the red to near-infrared wavelength range, especially for biological imaging applications.
Researchers from The University of Texas at Austin have developed a way to increase the light absorption of the quantum dots, while retaining the unique light-emitting properties of the quantum dots leading to a significantly brighter material.
These materials provide extremely bright light-emitting quantum dots in the far-red to near-infrared wavelength regions.
- Tunable light emission from red to near infrared wavelengths
- Extremely bright with high quantum yields (>40%)
- Surfaces can be modified with biological targeting molecules
- Long luminescence lifetimes to enable time-gated imaging methods
