摘要： PURPOSE:To improve transparency and gas barrier properties without impairing adhesive properties and to desirably use for a liquid crystal display element by forming a silicon oxide layer by a reduced pressure plasma chemical vapor depositing method using organic silicon compound gas and oxygen. CONSTITUTION:A laminate is obtained by laminating a silicon oxide layer 12 and a transparent conductive layer 13 on a transparent polymer base material 11 made of polyether sulfone, polyether ketone, etc. In this case, the layer 12 is formed by a reduced pressure plasma chemical vapor depositing method using at least organic silicon compound gas and oxide gas. The permeability of the oxygen gas of the laminate is desirably 0.1cc/m /14 hrs/latm. or less. The laminate is obtained by sequentially laminating the layers 12, 13 to the material 11 in the order of 12, 11 and 13, 11, 12 and 13, or 12, 11, 12 and 13. Thus, the laminate having transparency, flexibility and high gas barrier properties is obtained.

摘要： PURPOSE:To enhance performance, especially open terminal voltage, of an amorphous solar cell by placing a p-type gallium nitride thin film between a transparent electrode and a p-type semiconductor thin film. CONSTITUTION:An amorphous silicon solar cell is constituted of a translucent substrate 1, a transparent electrode 2, a p-type semiconductor thin film 4, an i-type semiconductor thin film 5, an n-type semiconductor thin film 6, and an electrode 7, laminated sequentially. A chemically stable semiconductor thin film having low resistance and very high transmittance of visible light is placed on a transparent conductive oxide between the transparent electrode 2 and the p-type semiconductor thin film 4. The p-type gallium nitride thin film 3 is preferably formed by 5-100Angstrom thick. This constitution realizes an amorphous solar cell having high open terminal voltage. Furthermore, conductivity type of gallium nitride can be easily controlled to p-type only through impurity control and thereby reverse n/p junction is relaxed, resulting in further improvement of open terminal voltage.

摘要： PURPOSE:To obtain an excellent monochromatic property of emission and a sufficient luminance by containing at least one layer of films of organic complexes of rare earth metals in a luminous layer in an injection type EL element. CONSTITUTION:Between a transparent conductive thin film layer 2 and a metal electrode thin film layer 5 on a transparent base 1, a hole conductive layer 3 and a luminous layer 4 are provided to form an injection type EL element. In this case, the luminous layer 4 is formed of an organic thin film containing at least one of thin film layers of organic complexes of rare earth metals. Namely, as the rare earth metals, 2-, 3- or 4-valence ions such as Y and La are sued. As the ligand of the organic material, those having beta-diketone groups such as acetyl acetone are used independently or in mixture thereof. These metal complex films and other organic thin films are laminated. For the organic compounds laminated, condensed polycyclic aromatic hydrocarbons such as rubrene are used.
