Abstract

A method and a device for generating light and to a use of a component for emitting light is disclosed. In a method for generating light, a component comprising a first material from the group of cuprates is subjected to an electric voltage and/or an electric field at a temperature T below 0° C. such that the component emits light. In this way, a light generation is provided which is accompanied by a substantial energy saving as well as a significantly reduced technical effort and which is also possible at cryogenic temperatures.
