PureFize presents field-emission cathodoluminescent approach for next-generation Far-UVC devices at ICFUST 2026
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.
Breakthrough results
The presentation at ICFUST 2026 concluded that 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:
- Deep-UV emission below 240 nm
- Tunable output power
- Wide-angle emission of approximately 100°
- Short start-up time
- Irradiance stability across a wide ambient temperature range
- Measured irradiance of approximately 3.5 µW/cm² at 1 m with 12 W total input power
How it works
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.
