摘要： The invention provides a tool to select reliable organic LED devices, where the risk for failure before the end of its lifetime is low. This tool comprises the steps of: i) subjecting the device to a high electric field over the electroluminescent layer. This leads to a division of the devices into two, clearly separated, populations, namely one population with a low leakage current (current through the electroluminescent layer in reverse voltage operation) and one population with a high leakage current. In this step, the first population is selected in accordance with a current criterion. ii) detecting instabilities in the leakage current, referred to as noise. It has been established that these instabilities arise in particular at reverse driving voltages between 1 and 10 Volts. These instabilities are a measure of the occurrence of early failures during operation. In this step, the devices are selected in accordance with a noise criterion.

摘要： A description is given of a switching device (1) comprising a transparent substrate (3), a reflective switching film (5) of yttrium having a thickness of 500 nm and a palladium layer (7) having a thickness of 5 nm. Using hydrogen gas at atmospheric pressure and at room temperature, a transparent, semiconductive film (5) of YH.sub.3 is formed, which is converted to a metallic mirror-like film (5) of YH.sub.2 by exposure to heat. The conversion of YH.sub.2 into YH.sub.3 is reversible and can for example be used in an optical switching element and in thin displays.
