Abstract

The invention relates to a microstructure glass substrate and a preparation method thereof. The microstructure glass substrate comprises a glass substrate layer and a photoelectric emission material layer, and the glass substrate layer is provided with grating groove structures distributed in a grid shape; the grating groove structure is formed by mutually crossing a plurality of grooves in a first direction and a plurality of grooves in a second direction, openings of the grooves face the photon emergent surface, and the grooves are filled with oxide film layers. The size of the grooves and the thickness of the photoelectric emission material layer meet the following relation: W*(delta+W)=1000*D, W is the width of the grooves, delta is the distance between two adjacent grooves, and D is the thickness of the photoelectric emission material layer. The emergent surface of the glass substrate is subjected to microstructure processing to form a grating with a special material structure, so that the photon propagation path is increased, and the spectral sensitivity is improved.

Description

technical field

[0001] The invention relates to the field of photoelectric conversion, in particular to a microstructure glass substrate and a preparation method thereof. Background technique

[0002] Photoelectric conversion is the basic link for photomultiplier tubes, photodiodes, and solar cells to realize their functions. Glass substrates have become an important material for receiving and transmitting photons because of their essential properties of spectral transmission. Divided into a photon incident surface and a photon exit surface, the photoelectric emission material is deposited on the photon exit surface of the substrate. Photoelectric conversion, the generated electrons are emitted from the other surface of the photoemissive material. In order to achieve more outgoing electrons, more photons need to pass through the substrate to reach the photoelectric emission material, and fully generate photoelectric conversion. However, there is an interface between the ph...
