    摘要： Disclosed is an improvement of the chemical vapor deposition (CVD) process for preparing an electroluminescent device having a large area and a large size. The process comprises forming a luminescent layer on a substrate by a reduced-pressure chemical vapor deposition method wherein a source material gas is introduced into a reaction chamber; an improvement being present in that;
    the reaction chamber includes a screening means which screens the source material gas flow in the chamber to form a first area in which the gas is flowing and a second area in which the gas substantially does not flow,
    the screening means has apertures for connecting the first area and the second area,
    the substrate is placed in the second area, to which the source material is supplied by means of gas diffusion.

    摘要： The present invention provides a thin film EL device comprising an electrode layer, an emitting layer and an electrode layer formed on a substrate one over another, and an insulating layer interposed between the three layers, the emitting layer containing atoms of a rare-earth element and fluorine atoms in its host material, the atom ratio (F/RE) of the fluorine atoms (F) to the rare-earth atoms (RE) being adjusted to the range of 0.5 to 2.5,
    and a process for producing the EL device being characterized in that the emitting layer is prepared by forming a film under a condition substantially free from oxygen gas and/ or moisture and subjecting the film to a heat treatment at a temperature of 200°C to 700°C so that the host material of the emitting layer contains atoms of a rare-earth element (RE) and fluorine atoms (F) in an adjusted atom raito (F/RE) in the range of 0.5 to 2.5.
    The present invention affords a thin film EL device which emits, for example, a green luminescence with a high brightness.
