Can you make led like device using metals
WebAdditionally, the device using the LED needs to operate efficiently. And for decades, blue was a challenge. Starting with their first commercial applications in the 1960’s, LED’s were used in low energy applications in the IR and near-IR for things like indicator lights, calculators and watches with low light output (mostly red). http://www.madehow.com/Volume-1/Light-Emitting-Diode-LED.html
