    Here is a link to an interesting IEEE Spectrum (the magazine of the Inst. of Electrical and Electronics Engineers) article on the Quantum-dot sensor technology.  It claims we should be seeing this in phone cameras within a couple of years.

    Read what Eric Fossum has to say about that:

    Also Eric’s remark in the comments section of the Spectrum article:

    I wonder if these articles are reviewed by others in the field before being published? The comment by Haynie is right on target. One should use current SOA when making comparisons. I do think quantum dot sensors will be good for many NIR and perhaps longer wavelength IR applications. But, because of the way the QD film works, sub-electron read noise and zero-lag operation is unlikely. Low noise and lag-free operation is expected from consumer image sensors so I don’t see QD based sensors replacing silicon visible light sensors in the near future. Sooner or later the current technology, which continues to evolve, will get replaced by something, but I wouldn’t bet on QD sensors for visible light. My personal favorite next gen sensors are photon counting image sensors – like the CMOS quanta image sensor or SPAD quanta image sensor – or perhaps even event-driven sensors or TOF sensors.
