Usually, due to its huge size a spectrometer is not portable.
TheseQuantum Dot spectrometersare small enough to fit inside the camera of a smartphone.
These nanocrytals were termed as Quantum dots.
Analgorithmwas then created by the researchers which analyzed the percentage of photons absorbed by each filter.
The information was recombined from each one to calculate the intensity and wavelength of the original rays of light.
It was found that the resolution was directly proportionate to the number of quantum dots.
Thus when thenumber of quantum dot materials is moreit coveredmore wavelengthsand in turn scientists were able toobtain higher resolution.
Besides, the tiny rig can also be used for tracking vital signs such as oxygen level and pulse.
QD spectrometer is portable, unique and quite advantageous in terms of flexibility, simplicity, and cost reduction.
