Is it possible to make a black colour LED?
That's really interesting. Have there been any practical applications for this technology?
Yes, there have been various uses for black LEDs. One such use is in night vision goggles, where the light emitted by the LED is invisible to the human eye, allowing for covert operations in the dark. They are also used in medical equipment, such as pulse oximeters, to measure blood oxygen levels without the need for a blood sample.
