Samsung patents sensor that detects UV and infrared light
Samsung has filed a patent for a sensor that can detect both ultraviolet and infrared light. The device uses a layer of quantum dots to turn infrared light into an electrical signal, while a filter blocks visible light from interfering with the readings.
In the filing’s own words
A sensor for detecting ultraviolet rays and infrared rays includes: a circuit board; a first electrode disposed on the circuit board; an electron transport layer disposed on the first electrode; an infrared ray photoelectric conversion layer disposed on the electron transport layer and including a quantum dot material for receiving light in an infrared ray region and generating photocharges; an ultraviolet ray photoelectric conversion layer disposed between the infrared ray photoelectric conversion layer and the hole transport layer; a hole transport layer disposed on the infrared ray photoelectric conversion layer; a second electrode disposed on the hole transport layer; and a visible light blocking filter disposed on the second electrode.
What exactly they claim (claim 1)
1. A sensor for detecting ultraviolet rays and infrared rays, the sensor comprising: a circuit board; a first electrode on the circuit board; an electron transport layer on the first electrode; an infrared ray photoelectric conversion layer on the electron transport layer, the infrared ray photoelectric conversion layer including a quantum dot material, the quantum dot material configured to generate photocharges based on receiving the infrared rays, the infrared rays including light in an infrared ray region; a hole transport layer on the infrared ray photoelectric conversion layer; a second electrode on the hole transport layer; and a visible light blocking filter on the second electrode.
