Spectroscopic Properties Of Pr³⁺-doped Boron Silicate Glasses

In21Century, science and technology change rapidly. People on radiation physics, high energy physics and nuclear physics researches are more and more deeply. The demand of various high-performance detectors, which is used for the particle identification, the determination of particle properties and the discovery of new particles, is also growing strongly. Therefore, the detector has more and higher request to the scintillator.However, there are still some problems unsolved with it, such as high equipment requirement, slow in crystal growth, high in price etc., so that the main drawback to it is the high cost. But the scintillating glass has the advantages of easy to prepare and process, composition easily adjusted, homogeneous microstructure, isotropic, easy casting, low cost etc. So it is easy to implement a large number of large size industrial productions. Then scintillating glass has become one of the research directions of scintillator materials. In recent years, people pay more and more attention to study on high-density oxide scintillating glass(HMO) doped with rare earth.This report shows the Pr3+-doped boron silicate scintillating glasses prepared by high temperature melting method and measured their emission spectra and transmission spectra. The results show that when the Pr3+doped in boron silicate glasses, their present a strong orange light of600nm, also the scintillating glasses with different concentrations of Pr3+have different emission intensity.
