and postdoctoral associate researcher Jakoah Brgoch appear in The Journal of Physical chemistry C. LED (light-emitting diode) lighting has been a major topic of research due to the many benefits it offers over traditional incandescent or fluorescent lighting.
LEDS use less energy emit less heat last longer and are less hazardous to the environment than traditional lighting.
and televisions LED TECHNOLOGY is becoming more popular as it becomes more versatile and brighter. According to Seshadri all of the recent advances in solid-state lighting have come from devices based on gallium nitride LEDS a technology that is largely credited to UC Santa barbara materials professor Shuji Nakamura who invented the first high-brightness
blue LED. In solid-state white lighting technology phosphors are applied to the LED chip in such a way that the photons from the blue gallium nitride LED pass through the phosphor
which converts and mixes the blue light into the green-yellow-orange range of light. When combined evenly with the blue the green-yellow-orange light yields white light.
