Multispectral imaging via luminescent down-shifting with colloidal quantum dots

The high infrared quantum yield, continuous absorption spectrum, and band edge tunability of colloidal quantumdots (QD) has opened up new opportunities to use luminescent down shifting for multispectral imaging in the infrared. We demonstrate a QD sensitized short wavelength infrared (SWIR) camera w...

Summary:The high infrared quantum yield, continuous absorption spectrum, and band edge tunability of colloidal quantumdots (QD) has opened up new opportunities to use luminescent down shifting for multispectral imaging in the infrared. We demonstrate a QD sensitized short wavelength infrared (SWIR) camera which is capable of UV-SWIR multispectral imaging. The application of multispectral cameras for UV tagging applications is demonstrated and the extension of this technology to the mid infrared spectral region is discussed.
