Abstract
We recently optimized a low-temperature, solvothermal synthesis method which yields luminescent, single-crystalline (Ca,Sr)S:Eu2+ particles. We now modified the process to allow direct growth onto templated substrates. The as-grown layers show a bright and homogeneous photoluminescence, peaking at 615nm and 650nm for SrS:Eu and CaS:Eu respectively. x-ray diffraction measurements proved that the layers grown at a temperature of only 200°C are strongly crystalline, with almost perfect (200) out-of-plane orientation. Scanning electron microscopy was used to study the morphology of the thin films. The electroluminescent properties of the thin films are discussed. The main advantages of this innovative approach for the production of TFEL devices are the low-temperature process and potential scalability.
