Some LEDs made from perovskite emit light over a broad wavelength range. To further explain the feature, scientists from the University of Groningen inspected some cases and proposed new explanation which may help other scientists to design perovskite LEDs capable of broad-range light emission. The study was published in the journal Nature Communications on May 11, 2020. Low-dimensional (2D or 1D) perovskites emit light in a narrow spectral range and are therefore used to make LED of superior color purity. However, in some cases, a broad emission spectrum at energy le...
