Process for treatment of a sapphire part with a beam of a mixture of mono- and multicharged ions of a gas which are produced by an electron cyclotron resonance (ECR) source, where: the voltage for acceleration of the ions is between 10 kV and 100 kV; the implanted dose, expressed in ions/cm.sup.2, is between (510.sup.16)(M/14).sup.1/2 and 10.sup.17(M/14).sup.1/2, where M is the atomic mass of the ion; the rate of displacement V.sub.D, expressed in cm/s, is between 0.025(P/D) and 0.1(P/D), where P is the power of the beam, expressed in W (watts), and D is the diameter of the beam, expressed in cm (centimetres). A part made of sapphire having a high transmittance and which is resistant to scratching is thus advantageously obtained.

A novel physical vapor deposition (PVD) layer structure for chrome-look coatings on plastic substrates shows very good adhesion. The PVD coating is embedded in an organic UV cured base coat applied to the substrate prior to PVD coating and a similar organic UV cured top coat to protect the PVD coating and to adjust the gloss level. The novel PVD coating structure consists of different metallic layers such as i.e. chromium, zirconium and aluminum and a new adhesion layer consisting of silicon monoxide (SiO) and silicon.

An electronic device may include conductive structures having a visible-light-reflecting coating. The coating may include a seed layer, transition layers, a neutral-color base layer, and an uppermost layer that forms a single-layer interference film. The neutral-color base layer may be opaque to visible light. The interference film may include silicon and may have an absorption coefficient between 0 and 1. The interference film may include, for example, CrSiN or CrSiCN. The composition of the interference film, the thickness of the interference film, and/or the composition of the base layer may be selected to provide the coating with a desired color near the middle of the visible spectrum (e.g., at green wavelengths). The color may be relatively stable even if the thickness of the coating varies across its area.

Disclosed herein is a method of preparing a white light-emitting material. The method of preparing a white light-emitting material includes the steps of: (a) depositing a metal for the formation of a blue light-emitting material on a substrate by performing thermal evaporation; (b) forming a material in which green and blue light-emitting materials are hybridized by placing the substrate, on which the metal film is deposited in step (a), in a plasma-enhanced chemical vapor deposition (PECVD) reactor and exposing the substrate to silicon (Si) and oxygen (O) in a plasma state; and (c) forming a red light-emitting material in the material formed in step (b) by annealing the material formed in step (b) so that the red, green and blue light-emitting materials are hybridized.

This application relates to a portable electronic device. The portable electronic device includes an enclosure having a metal oxide coating, the metal oxide coating including a metal alloy substrate that is doped with a dopant, and a metal oxide layer overlaying and formed from the metal alloy substrate so that the metal oxide layer includes the dopant.
