Abstract: A fluorescent nanocomposite which includes a thallium doped gadolinium chalcogenide having formula TlxGd1-xY, wherein x is 0.01 to 0.1, and Y is selected from the group consisting of S, Se, or Te, and a benzothiazolium salt bound to a surface of the thallium doped gadolinium chalcogenide. A method of detecting antimony ions in a fluid sample whereby the fluid sample is contacted with the fluorescent nanocomposite to form a mixture, and a fluorescence emission profile of the mixture is measured to determine a presence or absence of antimony ions in the fluid sample, wherein a reduction in intensity of a fluorescence emissions peak associated with the fluorescent nanocomposite indicates the presence of antimony ions in the fluid sample.

Abstract: Provided is an oxysulfide luminescent material. The luminescent material has a general chemical formula of Ln2−xO2S:Eux3+@My, wherein@ is coating, Eu is doped in Ln2−xO2S, Ln2−xO2S:Eux3+has a porous structure, and M is located in pores of the Ln2−xO2S:Eux3+. In the oxysulfide luminescent material, metal nano particles coating is used to form a core-shell structure, which increases luminescent efficiency of the oxysulfide luminescent material in a same excitation condition; in addition, a hollow structure is formed between a core and a shell layer of the oxysulfide luminescent material, which effectively reduces usage of rare earth elements in the shell layer and lowers cost of the luminescent material. Also provided is a preparation method for the oxysulfide luminescent material.

Abstract: A detector using scintillating crystals is provided. The scintillating crystal is based on cerium doped lutetium yttrium orthosilicate (Ce:LYSO). With calcium (Ca) doped into Ce:LYSO, the electrovalence of Ce is further uniformly distributed. The scintillating crystal obtains high stability with 2 to 10 times greater electrical degree than that of a general scintillating crystal. Thus, radiative induction to cancer cells is improved and distribution of the cancer cells is easily figured out.
