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.
Claims20
A method for generating light in which a component comprising a first material from a group consisting 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.
(canceled)
A device for generating light, comprising a component for emitting light and a power supply device for subjecting the component to an electric voltage and/or an electric field for emission of light by the component, wherein the component includes a first material from group consisting of cuprates, wherein the device is configured such that the component has a temperature (T) below 0° C. when light is generated.
The device according to thatclaim 13, wherein the device comprises cooling means for cooling the component to a temperature (T) below 0° C.
