  1. 1. Dynamics in Blue Emitting Metal Halide Perovskites for Light Emitting Diodes

    Författare :Max Karlsson; Feng Gao; Tze Chien Sum; Barry P. Rand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perovskites; Light-emitting diodes; Stability; Efficiency;

    Sammanfattning : Lighting comprises a large part of the global electricity consumption as of today, and the use of lighting in illumination and displays is only projected to grow. It is therefore imperative to meet this energy demand, not only by means of greener energy production, but also with materials that are both more efficient to fabricate as well as to use. LÄS MER
