A set of samples of electroluminescent (EL) lamps with ZnS phosphor was fabricated. These samples were degraded in different working conditions. Next, an attempt to rejuvenate these structures by annealing was undertaken. Several parameters of investigated structures were estimated. Then, measurements were performed after fabrication of test samples, their degradation and annealing. The luminance of the test structures as a function of applied voltage frequency was measured. Also, the spectrum of light emission before and after the degradation and rejuvenation processes was investigated.
