Abstract: Colloidal quantum dot devices are provided including an integrated circuit; a colloidal quantum dot structure on the integrated circuit; and an encapsulation layer on the colloidal quantum dot structure, the encapsulation layer having a thickness from about 0.5 nm to about 500 nm.

Abstract: Laser warning systems are provided for providing an alert when exposure to laser light sources is detected. The system includes a colloidal quantum dot detector module including a colloidal quantum dot photodetector and a processor coupled to the colloidal quantum dot detector module. The system detects interference patterns generated in the colloidal quantum dot detector module by light illuminating the laser warning system and determines if the light illuminating the laser warning systems is laser light based on a magnitude of interference infringes generated by the light illuminating the laser warning system.
