Ultraviolet phosphor, also known as ultraviolet phosphor or ultraviolet fluorescent pigment also called anti-counterfeiting powder, this kind of fluorescent pigment under ultraviolet light (200\ ~400nm) irradiation, according to the different metal, activator and content in the pigment, and present various colors of visible light (400\ ~800nm). According to the different wavelength of laser source, it can be divided into short-wave ultraviolet excited fluorescent pigment (excitation wavelength is 254nm) and long-wave ultraviolet excited fluorescent pigment (excitation wavelength is 365nm). Ultraviolet excited phosphor is a new type of material with wide application, which is widely used in anti-counterfeiting, lighting, display and other fields.

1. Core Features

Non-replicability: The technical threshold is high and the imitation cost is extremely high.

Combination of concealment and dominance: some features are visible to the naked eye (such as discoloration), and some need tool detection.

Durability: resistant to friction, temperature and humidity changes, suitable for long-term use.

2. Application Scenarios

Luxury goods and tobacco and alcohol: designer bags, high-end cigarette anti-counterfeiting labels.

Pharmaceuticals and electronic products: prevention of counterfeit medicines and refurbishment of electronic components.

Anti-counterfeiting ink
