The invention discloses an X-ray scintillation screen comprising a support layer, a fluorescent layer and a protection layer, wherein the support layer is connected with the fluorescent layer; the fluorescent layer is connected with an organic membrane layer; and the organic membrane layer is ...
X-ray scintillation properties To explore the scintillation performance of (C38H34P2)MnBr4, a commercially available scintillation material, cerium-doped lutetium aluminum garnet (Ce:LuAG), was used as a standard reference as it exhibits a similar PL emission peaked at ~520 nm that could min...
which act as scintillation loss channels. Here we found that X-ray-induced triplet excitons can be exploited for emission through very rapid, thermally activated up-conversion. We report scintillators based on three thermally activated delayed fluorescence molecules with different emission bands, which ...
In order to read out the large volume scintillation crystal by such a small photo-sensor as an avalanche photodiode, we have examined the light collection ... S Kobayashi,K Yamaoka,T Sato,... - 《Nuclear Instruments & Methods in Physics Research》 被引量: 6发表: 1996年 ...
x-ray衍射方法 五、多晶体/粉末X射线衍射 实际多晶样品是由数目极多的微小晶 粒组成，这些晶粒的取向完全是无规则的，各晶粒中指数相同的晶面取向分布于空间的任意方向。a)如果采用倒易空间的概念，则这些晶面的倒易矢量分布于整个倒易空间的各个方向，而它们的倒易阵点布满在以倒易矢量的长度为半径的倒易球面...
(Si). Here, we review all of the key properties of HPs, the relevant terminology necessary for radiation detection and scintillation, the physical mechanisms underlying their operation, the fabrication process, and perovskite crystals and thin-films of varying dimensionality used for high-energy ...
The emissive 1,1′-bi(2-naphthol-4,5-dicarboximide) (BiND-OH) and its phenyl/methyl derivatives, BiND-OPh and BiND-OMe, have been selected to investigate the structure-activity relationships between their crystal packing and X-ray scintillation properties. Single crystal X-ray diffraction ...
X-ray diffraction • X-rays discovered in 1895 – 1 week later first image of hand. • X-rays have l ~ 0.1 – few A • No lenses yet developed for x-rays – so no possibility of an x-ray camera or microscope. Instead, the diffraction pattern has all the information on amplitu...
This paper presents an investigation on the optical and scintillation properties for a set of fast inorganic scintillators. Transmittance, emission, light output, and decay time were measured. Based on this investigation, we plan to take two approaches to develop inorganic scintillators with sub...
In summary, we have reported a low-dose X-ray-induced photodynamic therapy based on purely organic phosphorescent nanoscintillators. By combining scintillation and energy transfer processes, scintillator nanoparticles are endowed with the ability to generate massive singlet oxygen upon X-ray irradiation,...
