The sulfide has the following composition, and the photoelectric element uses the sulfide. (1) The sulfide contains Cu, Zn, and Sn as a principal component. (2) When x is a ratio of Cu/(Zn+Sn), y is a ratio of Zn/Sn (x and y being atomic ratios), and the composition of the sulfide is represented by the (x, y) coordinates, with the points A=(0.78, 1.32), B=(0.86, 1.32), C=(0.86, 1.28), D=(0.90, 1.23), E=(0.90, 1.18), and F=(0.78, 1.28), the composition (x, y) of the sulfide is on any one of respective straight lines connecting the points A&#x2192;B&#x2192;C&#x2192;D&#x2192;E&#x2192;F&#x2192;A in that order, or within an area enclosed by the respective straight lines.

A light guiding plate guides light from a light source to illuminate a liquid crystal cell. A reflector reflects light from the light source. A first surface and a second surface selectively transmits or reflects light. A first region is formed on the first surface at a location that is relatively near the light source. The first region includes a first inclined face and a second inclined face. The first inclined face reflects light from the light source to guide light to the reflector. The second inclined face reflects light from the light source to the second surface so that the second surface emits light. A second region is formed on the first surface at a location that is relatively far from the light source. The second region includes a third inclined face and a fourth inclined face. The third inclined face reflects light from the light source to the second surface so that the second surface emits light. The fourth inclined face reflects light reflected by the reflector to the second surface so that the second surface emits light.

A recording medium includes a first substance and a second substance at least in which the first and second substances undergo an oxidation-reduction reaction when an external energy is applied, thereby recording information by varying the optical characteristics. In the recording medium, the reaction of the first and second substances is suppressed, reaction which degrades the recording characteristics other than the case where the recording medium is subjected to recording. In an optical disk (i.e., the recording medium), a WO film (i.e., a second substance), a C film (i.e., a third substance) and an Sn-10 atomic % Sr film (i.e., a first substance) are formed successively on a substrate . When the recording medium is irradiated with a recording laser beam as an external energy, the WO forming the film is reduced to WO , and the Sn-10 atomic % Sr forming the film is oxidized to SrO and/or SnO mainly with the WO and the Sn-10 atomic % Sr passing through the C film and/or destroying the C film . When the recording medium is not irradiated with the recording laser beam, the presence of the C film suppresses the reaction between the WO film and the Sn-10 atomic % Sr film

Memory member

In an optical disk which includes a recording film having a laminated construction, and which records information by changing optical characteristics of the recording film by applying a laser beam, there are laminatedly formed a WO film as a second layer, the WO requiring energy by about 470 kJ when it dissociates 1 mol of oxygen molecules, an Sn&mdash;43 atomic % Bi film which includes Sn as a first layer, the Sn generating energy by about 610 kJ when it bonds with 1 mol of oxygen molecules and having a melting point of about 139&deg; C., and a resin film in this order on a guide groove forming surface of a substrate When a recording laser beam is applied, a part of Sn&mdash;43 atomic % Bi film is turned into a liquid phase, both of the films and react, and the optical characteristics of the recording film vary so that information is recorded. As a result, the retention characteristic of the recorded data is secured, and the reactivity of the recording film is enhanced.

Storage member

A recording medium which includes a first substance and a second substance, wherein an external energy is applied to at least one of the first and second substances to react them in order to change the optical characteristics of the substances for recording information, the recording medium including: a first layer composed of a first substance including at least one of S and Se, a second layer composed of a second substance including a metal, and a barrier layer being disposed between the first and second layers, which allows the reaction between the first and second layers when laser beam for recording is irradiated as an external energy, and suppresses the reaction between the first and second layers when laser beam for recording is not irradiated. Alternatively, the recording medium can be free from the barrier layer, and the second substance can be arranged to have two or more compositionally different portions or two or more phases with a different crystalline state. Thus, when the external energy is not applied, the reaction between the first substance and the second substance is suppressed. Hence, the recording characteristics of the recording medium is inhibited from degrading.

Recording medium

A recording medium is for recording information by varying optical characteristic thereof by application of an external energy thereto, and includes a first substance and a second substance. When the external energy is applied to the recording medium, the first and second substances react with each other to form a third substance having a tungsten-bronze crystalline structure, thereby varying the optical characteristic. The third substance absorbs the external energy and varies the reflectivity of the external energy. Thus, the recording medium records information thereon. The recording medium is good in environmental resistance and information retention, because the third substance is stable energetically.
