A team of researchers from the Tokyo Institute of Technology (Tokyo Tech) has developed a single-component white light-emitting diode (LED) utilizing codoping of perovskites. This breakthrough could have a wide range of applications in lighting, display, and bioimaging.

For the past decade, scientists have been attempting to create a single-component white light LED. The challenge has been to combine the three primary colors of light (red, green, and blue) into a single device. Now, researchers from Tokyo Tech have achieved this goal using a codoped perovskite material. This groundbreaking material is composed of a single component, which is a combination of lead iodide, bromide, and chlorine. This mixture produces a bright white light with minimal color distortion and high color rendering. The researchers are now exploring further applications of this material in various fields.
