Originální abstrakt

Fluctuations of current and light emission in electroluminescent lamps based of zinc sulfide phosphor powder embedded in a dielectric layer are presented. Noise sources are emission of electrons from localised levels in the gap, impact excitation and impact ionisation of luminiscence centers and radiative transition by hot carriers. Due to high electric field, partial discharges are also sources of current fluctuations. Crystal defects, such as pores, grain boundaries and dislocations may provide regions, where a localised continuum of states bridges the energy gap and allow non-radiative recombination, which is related to current fluctuation. Noise spectroscopy is used to estimate the quality and reliability of thick electroluminiscent layers. In these devices, the overall efficiency is further degraded by absorption, internal reflection and other losses. Brightness versus applied voltage and frequency is used to describe the degradation process and correlation with noise spectral density was used to estimate the quality and reliability of these devices.
