Title: Innovations of George Chik

Introduction

George Chik is a notable inventor based in Nepean, Canada. He has made significant contributions to the field of solid-state light emitters, holding a total of 5 patents. His work focuses on engineered structures that enhance the efficiency and brightness of light-emitting devices.

Latest Patents

One of his latest patents is titled "Engineered structure for solid-state light emitters." This invention describes a light-emitting device that consists of multiple layers of alternating active and buffer materials situated between AC or DC electrodes. These layers generate an electric field, with the active layers containing luminescent centers, such as group IV semiconductor nanocrystals, embedded in a host matrix like silicon dioxide or silicon nitride. The buffer layers are designed to ensure that electrons passing through them gain sufficient energy to excite the luminescent centers in the adjacent active layer, allowing for efficient light emission at a desired wavelength.

Another significant patent is "Engineered structure for high brightness solid-state light emitters." This invention involves electroluminescent light-emitting structures that include one or more active layers with rare earth luminescent centers in a dielectric host matrix. The design allows for the emission of light in specific colors or wavelengths, with electrodes facilitating the application of an electric field and current injection. The structure can be optimized for efficient impact excitation, and a stack of active layers can be combined to produce white light.
