Far-UVC is attracting increasing scientific and commercial interest because of its potential to inactivate microorganisms in air and on surfaces. PureFize’s core technology can be directed toward Far-UVC, opening a path toward scalable, flexible and potentially application-specific device designs.
Broad market adoption will require technologies that can deliver the right combination of wavelengths, stability, manufacturability, cost, integration flexibility, and application-specific performance. Early prototype characterization presented by PureFize showed:
PureFize’s demonstrated concept is based on the company’s established field-emission/cathodoluminescence platform. In the device, electrons are emitted from a nanostructured cathode and accelerated toward a phosphor-coated surface. When the electrons interact with the phosphor material, emission is generated through cathodoluminescence. By changing the phosphor material, the emission spectrum can be engineered for different UV ranges and applications.
