UV anti-counterfeit photoelectric detector barcode scanner chip, preparation method thereof, and scanning gun

Abstract

The invention discloses a UV anti-counterfeit photoelectric detector barcode scanner chip, a preparation method thereof, and a scanning gun. The UV anti-counterfeit photoelectric detector barcode scanner chip comprises a photoelectric detector, wherein the photoelectric detector comprises a package structure formed by a casing and an optical filter, and a photoelectric sensor disposed in the package structure; the photoelectric sensor comprises a first electrode, a first silicon substrate, a single layer of boron nitride, a cuprous iodide film, and a second electrode which are stacked in orderfrom bottom to top. The UV anti-counterfeiting high-sensitivity photoelectric sensor barcode scanner chip of the invention improves the capability of the photoelectric detector to acquire weak light,can achieve a photoelectric response range from infrared light to ultraviolet light, and can be applied to the field of ultraviolet anti-counterfeiting.

Description

technical field [0001] The invention relates to the field of photoelectric detectors, in particular to an ultraviolet anti-counterfeiting photoelectric detector barcode scanner chip, a preparation method thereof, and a scanning gun. Background technique [0002] The photoelectric sensor barcode scanning chip can convert the optical signal of the scanned barcode into a matching electrical signal. After the electrical signal is shaped and amplified, a digital signal that can be recognized by the decoder is obtained. The decoder obtains the complete barcode information according to the decoding rules. Transfer it to the computer screen to display it. The photoelectric sensor barcode scanning chip is assembled on the scanning gun, and is now widely used in logistics, supermarkets, postal services and other fields. At present, most of the photoelectric sensor barcode scanning chips on the market use ordinary silicon chips to form photoelectric signal sensing units. Although they...
