Different coloured Light Emitting Diodes (LEDs)
Blue diode. View of a hand holding the worlds first marketed blue light emitting diode (LED) made from gallium nitride. It is shown with different coloured LEDs. The only blue LEDs available before this were based on silicon carbide. These were very inefficient and did not glow very brightly. LEDs are made of two thin film layers that contain specific impurities which give them opposite electrical properties. An electric current passing through the LED will make it produce light. LEDs were developed in the 1960s but could initially only produce red or green light. In 1995 the Nichia corporation of Japan first marketed these blue LEDs.

EDITORS COMMENTS
This print showcases a groundbreaking moment in the world of technology. In the center, we see a hand holding the world's first marketed blue light emitting diode (LED) made from gallium nitride, surrounded by an assortment of different colored LEDs. Prior to this innovation, blue LEDs were based on silicon carbide and proved to be inefficient and dimly lit. However, with the introduction of gallium nitride technology, a new era has dawned. The significance of this achievement lies in the fact that LEDs are composed of two thin film layers containing specific impurities that give them opposite electrical properties. When an electric current passes through these LED layers, they emit light. Initially limited to producing red or green light since their development in the 1960s, it was not until 1995 when Nichia corporation from Japan introduced these revolutionary blue LEDs. This photograph captures both the scientific breakthrough and aesthetic beauty of LED technology. The vibrant array of colors surrounding the pioneering blue LED serves as a visual testament to human ingenuity and progress in electronics. It reminds us how far we have come from humble beginnings while also hinting at endless possibilities for future advancements in lighting and display technologies.
