Colloidal quantum dot light emitters go broadband in the infrared

Broadband light emission in the infrared has proven to be of paramount importance for a large range of applications that include food quality and product/process monitoring, recycling, environmental sensing and monitoring, multispectral imaging in automotive as well as safety and security. With the advent of IoT and the increasing demand in adding more functionalities to portable devices (such as smart watches, mobile phones etc.) the introduction of on-chip spectrometers for health monitoring, allergen detection food quality inspection, to name a few, is expected to happen soon. But in order to have such functionalities easily integrated and implemented in mass production consumer electronics, several prerequisites need to be met. More specifically, the light source needs to be compact, highly efficient and ideally CMOS integrated to guarantee low-cost and high volume manufacturing.
