"The aim of this study was to extend recent research employing the photoacoustic measurements to multilayer samples of a printed electronic device. For this purpose, samples of the electroluminescent source based on a light emitting capacitor, consisting of up to six layers (including flexible substrate), were produced by the screen-printing. The samples with four combinations of different luminescent and insulating layer thicknesses were prepared and examined both with respect to their performance and to the possibility of the photoacoustic characterization of the finished panel as well as of individual intermediate products. The examination of the functionality of prepared electroluminescent panels showed that both the luminance and its homogeneity within the active area are significantly influenced by the thickness of the active layer. The study proved that all samples, ranging from the unprinted substrate with ITO layer over the prints of individual functional layers to the complete panels, are measurable by means of the photoacoustics using excitation sources with visible wavelengths and with intensity modulation in the range between 10 Hz and 1 kHz. The capability of the photoacoustics to depth-profile the samples with varying multilayer structure was shown."@en . "978-3-9812704-5-7" . . "25310" . . "158529" . . . "Ljubljana" .
