They help in detecting diseases like cancer and in the treatment of various conditions. 3. Agriculture: In agriculture, FIRLEDs are used to monitor plant health and growth by detecting temperature and moisture levels. 4. Food Safety: FIRLEDs are used to detect spoilage and contamination in food products, ensuring safety and extending shelf life. 5. Environmental Monitoring: FIRLEDs are used in environmental monitoring systems to detect pollutants and monitor air quality.

Technology Behind FIRLEDs

The technology behind FIRLEDs involves the use of semiconductor materials that can emit infrared radiation when an electric current is applied. The key components of FIRLED technology include: 1. Semiconductor Materials: FIRLEDs are typically made from semiconductor materials such as gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide (InGaAs). These materials have band gaps that correspond to the infrared region of the spectrum. 2. Device Structure: FIRLEDs consist of a p-n junction, where the p-type and n-type regions are formed by doping the semiconductor material. The electric current flows through this junction, causing electrons to recombine with holes, releasing energy in the form of infrared light. 3. Optical Design: The optical design of FIRLEDs is crucial for efficient light emission and collection. This includes the use of lenses, mirrors, and other optical components to focus and direct the emitted light.
