Abstract

Razelektritvena sijalka s hladno katodo brez živega srebra, ki je znana kot neonska cev in uporablja pline brez živega srebra kot vir ultravijoličnih žarkov, ki vzbujajo sloj z luminescentnim premikom navzdol (LDS) za generiranje vidne svetlobe. Material z luminescentnim premikom navzdol (LDS) absorbira UV sevanje, z višjim izkoristkom kot fosforji, in ponovno emitira svetlobo z daljšo valovno dolžino, v vidnem spektru.A mercury-free cold-cathode discharge lamp, known as a neon tube, uses mercury-free gases as a source of ultraviolet rays to excite a luminescent downshift (LDS) layer to generate visible light. Luminescent Down Shift (LDS) material absorbs UV radiation with higher efficiency than phosphors and re-emits longer wavelength light in the visible spectrum.
