Abstract
The present invention relates to a light emitting device comprising a first main layer of an electrically conducting material, a second main layer of an electrically conducting material and a light emitting unit between the first main layer and the second main layer, wherein the light emitting unit comprises a light emitting layer, and wherein the first main layer and/or the second main layer has a light exit orifice aligned with a section of the light emitting layer. The light emitting device can utilise impact ionisation to emit UV-C light.
Claims17
A light emitting device comprising a first main layer of an electrically conducting material, a second main layer of an electrically conducting material and a light emitting unit between the first main layer and the second main layer, wherein the light emitting unit comprises a light emitting layer comprising a crystal of MgO with a crystal orientation of <111>, and wherein the first main layer or the second main layer has a light exit orifice aligned with a section of the light emitting layer.
A method of producing a light emitting device, the method comprising the steps of providing a substrate comprising a first dielectric layer, selecting a deposition process from a list consisting of:
- chemical vapour deposition (CVD) process, metal organic chemical vapour deposition (MOCVD) process, atomic layer deposition (ALD) process, and e-beam deposition process, depositing a crystal of MgO <111>orientation on the substrate to provide a light emitting layer, providing a first main layer of an electrically conducting material and a second main layer of an electrically conducting material, positioning the light emitting layer between the first main layer and the second main layer, and providing the first main layer or the second main layer with a light exit orifice aligned with a section of the light emitting layer.
