    UC Berkeley perovskite LED

     Scientist at University of California, Berkeley (UC Berkeley) have created a blue LED from a new semiconductor material halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.


    Published in Science Advances on January 24, the study demonstrates the technology breakthrough of applying the unstable material as halide perovskite changes with temperature, humidity and the chemical environment and their optical and electronic properties are thus disrupted.

     

    Making semiconductor diodes that emit blue light has always been a challenge, noted Peidong Yang, UC Berkeley chemist who led the research. So far, red- and green-emitting diodes made from perovskites have been demonstrated, but not blue. Halide perovskite blue-emitting diodes have been unstable, that is, their color shifts to longer, redder wavelengths with use.
