Abstract
A wavelength conversion layer comprises a metal sub oxide matrix with a low organic dye molecule content. A wavelength conversion layer, for producing light in the optical and adjacent spectral regions, comprises a metal oxide matrix material which has a slightly sub stoichiometric oxygen content and which contains a small concentration of organic dye molecules. Independent claims are also included for the following: (i) production of the above wavelength conversion layer by co-evaporation of organic dye and metal oxide onto a substrate; and (ii) an apparatus for carrying out the above production process.
| Translated title of the contribution | Wavelength conversion layer, e.g. for white light production, light coupling or radiation detection or as an ideal point light source, comprises a metal sub oxide matrix with a low organic dye molecule content |
