    摘要: A recording member e.g. an optical video disc, comprises a substrate and a recording layer formed on the substrate. To achieve improved oxidation resistance and water resistance and stable characteristics, the recording layer contains Se and at least one of Te and Bi, the Se content in the vicinity of the outer surface of the recording layer and/or in the vicinity of the interface between the recording layer and the substrate being higher than the average selenium content in the remainder.

    摘要: An electrophotographic plate consists of a substrate (1) with a conductive surface and four successive layers (2,3,4 and 5) the third of which is optional. The first layer (2) is formed from Se and 3 to 10%by weight of As, and the second layer (3) is formed from Se, 40 to 47% by weight of Te and 3 to 10% by weight of As. The fourth layer (5) may be formed from an organic semiconductor Se only, or Se and up to 10% by weight of As. The conductive surface of the substrate (1) may be closest to the first layer (2) or to the fourth layer (5). This electrophotographic plate is sensitive to radiation with wavelengths longer than 700 nm and therefore permits the use of a semiconductor laser in an electrophotographic device. In making the plate, the substrate is maintained between 50°C and 80°C at least whilst the fourth layer (5) is formed, thereby to reduce the residual potential. All the layers are formed independently.

    摘要: An electrophotographic member has a support (1) and a photoconductor layer (2) on the support formed mainly of amorphous silicon. Improved characteristics of the layer (2) are obtained when the amorphous silicon contains on average at least 50 atomic-% silicon and at least 1 atomic-% hydrogen and a surface part (23, 25) at least 10 nm thick extending from a surface of the layer toward its interior has a hydrogen content of 1 to 40 atomic-% an optical forbidden band gap of 1.3 to 2.5 eV and an infrared absorption spectrum in which the intensity of at least one of the peaks centered approximately at wave numbers 2,200 cm -1 , 1,140 cm -1 , 1,040 cm -1 , 650 cm -1 , 860 cm- 1 and 800 cm -1 and attributed silicon-oxygen bonds does not exceed 20% of the intensity of the higher of the peaks centered at approximately wave numbers 2,000 cm-1 and 2,100 cm -1 and attributed silicon-hydrogen bonds. Dark decay characteristics are good, and a satisfactory surface potential can be achieved. In addition, the characteristics of the member are stable with time.
