Abstract

The invention discloses a chemical constitution of a glass film containing rare earth ion-doped Cs2LiYCl6 microcrystalline and a sol-gel preparation method of the glass film. The glass film is characterized by comprising the following components by mol percent: 71mol%-75mol% of germanium dioxide, 5mol%-10mol% of aluminum sesquioxide, 5mol%-10mol% of phosphorus pentoxide, 8mol%-12mol% of Cs2LiYCl6 and 1mol%-3mol% of rare-earth chloride, wherein rare-earth chloride is one of cerium chloride, europium chloride or terbium chloride. The sol-gel preparation method has the advantages that sol-gel is a low-temperature wet chemical method glass preparation technique, and glass is prepared by virtue of hydrolysis and chemical polymerization reaction of precursor raw materials, and a film material can be prepared under certain liquid viscosity; by virtue of low temperature synthesis conditions, the decomposition and the volatilization of the chloride raw material can be effectively prevented.

Description

technical field

[0001] The invention relates to a glass-ceramics film doped with a rare earth ion, in particular to a Cs doped with a rare earth ion used as a scintillation material 2 LiYCl 6 Microcrystalline glass thin film and its preparation method. Background technique

[0002] Scintillation material is a photofunctional material that can emit visible light under the excitation of high-energy rays (such as x-rays, γ-rays) or other radioactive particles, and can be widely used in nuclear medicine diagnosis, security inspection, anti-terrorism, high-energy physics and geological exploration and other fields. In recent years, with the rapid development of fields such as medical imaging and security inspection, there is a large demand for new scintillation materials with high performance. Excellent scintillation materials mainly have the following properties: high luminous efficiency, high material density, fast fluorescence decay, good radiation resistance and low produc...
