AlGaN-based far ultraviolet-C (UVC) light emitting diodes (LEDs) with a peak emission wavelength below 240 nm typically show a long-wavelength tail at >240 nm that is detrimental to the use of the devices for skin-friendly antisepsis. We present the

Higher optical power and higher UV doses come along with a higher operation temperature of UV LED based light sources. Silver sintered pastes offer a robust lead-free alternative to solder pastes increasing the lifetime of the device and enabling hig

The usage of UV LEDs is getting attractive for application such as phototherapy, plant growth, and disinfection due to the wavelength selective, narrow-band emission and a high potential for miniaturization of LED devices. Besides these benefits, the

Characterising the amount and the purity of nucleic acid is an important step in state of the art polymerase chain reaction (PCR). In most cases, the analysis is done by stand-alone equipment. For the measurement, a small amount out of the PCR-proces

UV LEDs are usually mounted in flip-chip technology by soldering or thermocompression bonding to allow the UV light to be emitted through the sapphire substrate. The thermal conductivity of solders is considerably smaller than that of the typical met
