Abstract
Polymeric organic coating for electroluminescent lamp components, particularly for phosphor particles and electrodes and a method of making same, wherein the polymer is formed using an initiator, preferably by ring-opening metathesis polymerization. A dense hydrophobic organic coating is formed which is capable of protecting the electroluminescent device components from exogenous agents such as moisture and eventual degradation. The polymer layer may be attached to an outer surface of the component by one or more tethering layers.
Claims14
An electroluminescent lamp, wherein a component of the lamp has a hydrophobic, polymeric organic coating, comprising
- a tethering layer on the exterior of the electroluminescent lamp component;
- and
- a hydrophobic organic polymer coating covalently bound to the tethering layer.
An electroluminescent lamp assembly comprising electroluminescent components of made by a method comprising
- forming a tethering layer of small molecules on an outer layer of the components, wherein the tethering layer has a plurality of initiator groups external to the tethering layer surface;
- and
- polymerizing hydrocarbon monomers from the initiator groups to form a hydrophobic, organic polymeric coating attached to the tethering layer.
An electroluminescent lamp, wherein a component of the lamp has a hydrophobic, polymeric organic coating, comprising
- a hydrophobic organic polymer coating covalently bound to a metal oxide disposed on an outer surface of the component.
