Abstract

The invention belongs to the field of photoelectric functional materials and particularly relates to diamagnetic chalcogenide magneto-rotation optical glass and a preparation method thereof. The glass is prepared from, by molar mass, 60-80% of GeS2, 15-20% of In2S3 and 0-25% of PbI2. The verdet constant of the magneto-rotation optical glass is up to 0.287min.G<-1>.cm<-1>@632.8nm and higher than that of existing diamagnetic glass, and the magneto-rotation optical glass is wide in application. The magneto-rotation optical glass belongs to diamagnetic chalcogenide magneto-rotation optical glass, and the verdet constant of the magneto-rotation optical glass is unrelated to the temperature, so that a device prepared from the diamagnetic chalcogenide magneto-rotation optical glass is free of a temperature compensation system and is simple in structure and high in stability. Breakthrough curves of the diamagnetic chalcogenide magneto-rotation optical glass cover four wave bands including a visible wave band, a near-infrared wave band, an intermediate infrared wave band and a far-infrared wave band, and the diamagnetic chalcogenide magneto-rotation optical glass is especially suitable for magnetic-optical devices in intermediate-infrared and far-infrared wave bands.

Description

technical field [0001] The invention belongs to the field of photoelectric functional materials, and in particular relates to a diamagnetic chalcogenide magneto-optical glass and a preparation method thereof. Background technique [0002] The magnetorotation effect is also known as the Faraday effect, that is, when linearly polarized light propagates in a medium, if an additional magnetic field is added parallel to the propagation direction of the light, the direction of the vibration plane of the light will be deflected, and the rotation direction of the polarization plane depends only on The direction of the magnetic field has nothing to do with the direction of light propagation. Magneto-optical glass based on the Faraday effect has important applications in magneto-optical isolators, magneto-optical switches, magneto-optical modulators, and optical fiber current sensors. For example, the magneto-optical isolator made of magneto-optical glass can eliminate harmful reflec...
