Blue_LED.jpg (286 × 383 pixels, file size: 10 KB, MIME type: image/jpeg)
A blue light emitting diode (LED) is seen here. Blue and ultraviolet LEDs are made using InGaN and GaN semiconductors. Currently, white LEDs are often made using a phosphor coating which is optical pumped by InGaN and GaN active materials.
