Engineers Develop New White LED
Engineers at the University of California San Diego discovered a new phosphor material for the development of white LEDs, on February 19, 2018.
The team used data mining and computational tools to create such a material. These LEDs are inexpensive and extremely easy to make. They built a prototype white LED light bulbs making use of the new phosphor.
The prototypes exhibited better color quality than many commercial LEDs currently available.
Phosphors emit light and are one of the key ingredients to produce white LEDs. These crystalline powders, known to absorb energy from blue or near-UV light, usually emits light in the visible spectrum. The combination of the different colored light creates white light.
The new phosphor is made of the elements strontium, lithium, aluminum, and oxygen. The team used supercomputers to predict SLAO. Calculations predicted this material would be stable and perform well as an LED phosphor.
The LEDs were evaluated using the Color Rendering Index (CRI), a scale that rates from 0 to 100 how accurate colors appear under a light source.
