  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.

  一种荧光纳米复合材料，它包括一种掺铊的掺钆铬化物，其式为TlxGd1-xY，其中x为0.01至0.1，Y选自由S、Se或Te组成的组，以及一种与掺铊的掺钆铬化物表面结合的苯并噻唑盐。一种检测流体样品中锑离子的方法，其中流体样品与荧光纳米复合材料接触以形成混合物，测量混合物的荧光发射曲线以确定流体样品中是否存在锑离子，其中与荧光纳米复合材料相关的荧光发射峰强度降低表明流体样品中存在锑离子。
