Abstract
Official abstract text for this publication.
The described embodiments relate generally to cosmetic surfaces and associated treatments to alter a color of cosmetic surfaces. According to one embodiment, cosmetic ink configured to be applied to a cosmetic surface can include a suspension matrix configured to suspend a number of small particles in the suspension matrix. Each of the small particles of the is within a desired overall diameter to cause a user to perceive a desired color due to plasmon resonance of the small particles.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic device having an anodic film, the anodic film comprising: silver nano-particles deposited within pores of the anodic film, the silver nano-particles having diameters sufficient for causing light incident the silver nano-particles within the anodic film to reflect wavelengths of light by plasmon resonance, at least some of the silver nano-particles characterized as having a triangular or hexagonal shape, wherein the diameters of the silver nano-particles and the shape are sufficient to cause a peak plasmon resonance around 550 nanometers associated with imparting a red color to the anodic film. 2. The electronic device of claim 1 , wherein the at least some of the silver nano-particles are coated with a sizing layer. 3. The electronic device of claim 2 , wherein the sizing layer is comprised of silica. 4. The electronic device of claim 1 , wherein the first portion of the silver nano-particles is coated with a first type of sizing layer and a second portion of the silver nano-particles is coated with a second type of sizing layer different than the first type of sizing layer. 5. An electronic device having an anodic film, the anodic film comprising: silver nano-particles deposited within pores of the anodic film, the silver nano-particles having diameters sufficient for causing light incident the silver nano-particles within the anodic film to reflect wavelengths of light by plasmon resonance, at least some of the silver nano-particles characterized as having a triangular or hexagonal shape, wherein the diameters of the silver nano-particles and the shape are sufficient to cause a peak plasmon resonance around 750 nanometers associated with imparting a blue color to the anodic film. 6. An electronic device having an anodic film, the anodic film comprising: silver nano-particles deposited within pores of the anodic film, the silver nano-particles having diameters sufficient for causing light incident the silver nano-particles within the anodic film to reflect wavelengths of light by plasmon resonance, at least some of the silver nano-particles characterized as having a triangular or hexagonal shape, wherein the diameters of the silver nano-particles and the shape are sufficient to cause a peak plasmon resonance around 950 nanometers associated with imparting a green color to the anodic film.
