High power deep UV-LEDs for analytical optical instrumentation
Popis výsledku v původním jazyce
Light emitting diodes (LEDs) have been extensively used in portable, LEDs suffer from low optical power and parasitic emissions in the visible wavelength range. Recently, newly developed deep UV-LEDs based on aluminium nitride (AlN) substrates have been introduced claiming improved performance, however there is little in terms of systematic evaluation of their performance parameters when used as light sources in chemical sciences. The aim of this work was to investigate the performance of these new generation deep UV‐LEDs, and assess their analytical applicability. Their emission spectra, optical output power values and energy conversion efficiency (electrical/optical) were investigated. This work shows effects of forward current and voltages on the ratio of intensities of the visible parasitic emission to the desirable deep UV emission. The performance was demonstrated by detection of four parabens separated by miniaturised capillary liquid chromatography.
