RADIATION EMITTING DEVICE AND MANUFACTURING PROCESS THEREOF

摘要

The present invention relates to an electromagnetic radiation emitting device (LED 140) comprising at least one layer made of semiconductor material suitable for emitting a first electromagnetic radiation centered at a first wavelength and at least one wavelength converter layer (150) coated on said at least one layer made of semiconductor material. The wavelength converter layer is provided for at least partially converting the first electromagnetic radiation so that the resultant electromagnetic radiation is emitted by said emitting device centered at a second wavelength different from said first wavelength, the material (130) of the wavelength converter layer comprising nanostructured silicon (120). Furthermore the present invention relates to a manufacturing process of said device.
