According to reports, researchers at Arizona State University (ASU) are developing a high-quality O led lighting device that does not emit ultraviolet light . Since ultraviolet light can suppress the human eye from clearly distinguishing color changes and object textures, this O LED will be particularly applied to museums, art galleries, and the like.
The high-quality white light emitted by the organic light-emitting diode (OLED) on the cube shows how the OLED vividly illuminates all colors of the visible spectrum over the entire range of the cube, from blue to green, yellow and red. (Source: ASU)
Recently, researchers received grants from the US Department of Energy (DoE) for $875,000 to expand the study. The team is working closely with Universal Display to develop an OLED that uses a single luminescent material to create white light instead of a red, green, blue (or yellow and blue) combination of luminescent materials. Led device .
It is reported that the new design uses a single molecule that emits blue light. The molecule is stacked with two other molecules to emit orange light. This material emits white light if placed properly.
