Quantum Dot Camera Phones

Abstract:
InVisage, a Menlo Park, CA-based startup, is demonstrating a way to improve the quality of pictures, at least on the sensor side, without adding size, significant complexity, or cost. At the DEMO conference in Palm Springs, CA, today, the company's executives announced a new technology called QuantumFilm that lets small camera sensors, like those in cell phones, capture more light than ever before. QuantumFilm is simply a layer of quantum dots--tiny crystals that efficiently absorb light and emit either photons or electrons--in a top layer of the sensor. The electrons emitted by QuantumFilm are collected and sorted the chip's circuitry.
