quantum-dot spectrometer

The new quantum dot spectrometer deploys hundreds of quantum dot materials that each filter a specific set of wavelengths of light. The quantum dot filters are printed into a thin film and placed on top of a photodetector such as the charge-coupled devices (CCDs) found in cellphone cameras.

The researchers created an algorithm that analyzes the percentage of photons absorbed by each filter, then recombines the information from each one to calculate the intensity and wavelength of the original rays of light.

The more quantum dot materials there are, the more wavelengths can be covered and the higher resolution can be obtained. In this case, the researchers used about 200 types of quantum dots spread over a range of about 300 nanometers. With more dots, such spectrometers could be designed to cover an even wider range of light frequencies.

If incorporated into small handheld devices, this type of spectrometer could be used to diagnose skin conditions or analyze urine samples, Bao says. They could also be used to track vital signs such as pulse and oxygen level, or to measure exposure to different frequencies of ultraviolet light, which vary greatly in their ability to damage skin.

 

 

I guess now. now you can see next generation of wearables tracking much more tan currently possible

analyze urine samples....

I see it now on the app store

Nice. Spectrometers are used so much, we have plenty of old ones on our lab.

Quantum dots are quite amazing as well, solar panels and such are also possible to make from them.

And they aren't even that hard to make (although the name might make you suspect other wise)

Ooooo this could tie in nicely with a product we're developing ATM

This is the intermediate step between LCD and OLED, if used for displays.

 

Since LCD was milked for so long we have already put the superior OLED in momentum.

 

Anything that has to do with quantum dots is already obsolete due to OLED technologies.

I know that these companies are sad that they missed an opportunity to milk us for a marginal upgrade for another 20 years. What can i say - fuck em.

This has nothing to do with display
