More Information
Summary:The present invention relates to light emitting, display and scintillation material technology, and is especially one kind of light-emitting Pr doped tungstate material and its use. The light-emitting Pr doped tungstate material may be in monocrystal, powder or glass form. By means of the quantum cutting of Pr3+ ion and the energy transfer between tungstate radical and Pr3+ ion, one photon in deep ultraviolet area or in even short wavelength area is converted into two visible photons for human eye and CCD to sense, so as to realize quantum cutting to the 490-650 nm visible light area in the total quantum efficiency over 100 %. The light-emitting Pr doped tungstate material is used as the ultraviolet and even short wavelength ray excited light emitting material and the scintillation material in short wavelength photon detector and high energy particle detector.
