Silanna
UV Presents High Power 235nm far UVC LEDs Using New SPSL Technology
ICULTA
Berlin UV LED conference to see high power at short wavelengths and
exceptional lifetime
Brisbane, Australia, 6
April 2023 - New technology that pushes the boundaries of
far UVC LEDs to emit at shorter wavelengths, at higher power, and with
longer lifetimes, will be presented by Silanna UV at the International
Conference on UV LED Technologies & Applications (ICULTA) in
Berlin, Germany from April 23 to 26, 2023.
On April 24, from 10.00-10.30am, William Lee, Silanna UV’s Product
Development Manager, will give a talk, “High Power 235nm far UVC LED
using SPSL technology". The company’s SF1 series 235nm and SF3 series
255 nm UV LEDs will be exhibited. Silanna is a Silver sponsor of the
conference.
New
UV-C LED technology
This revolutionary UVC LED technology from Silanna UV offers huge
advantages for applications as diverse as disinfection, water quality
monitoring, gas sensing, liquid chromatography, and chemical and
biological analysis.
Old-fashioned AlGaN-based far UVC LEDs in general suffer from poor
carrier injection, low light emission and high drive voltage, due to
the inherit limitations of high Al-content AlGaN.
Silanna’s new short period superlattice (SPSL) far UVC LED structure
helps overcome these issues. In a SPSL device, composed of repeating
layers of AlN and GaN, the presence of GaN maintains the TE dominance
of the emission as well as lowering the activation energy of donors,
resulting in more efficient devices compared to LEDs made with the
conventional AlGaN technology. Furthermore, the emission wavelength can
be easily tuned using the thickness of the GaN well, a process that is
significantly easier to control than tuning of Al composition in the
barrier and well.
