摘要： 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.

摘要： The present subject matter relates to water-soluble, fluorescent compounds that have aggregation-induced emission (AIE) characteristics and exhibit near infrared (NIR) absorption. The compounds can be utilized as plasma-membrane specific bio-probes in cell imaging through a wash-free and fast staining procedure. In addition, the compounds can efficiently generate reactive oxygen species (ROS) in vivo when irradiated with visible light. As such, the compounds can be effective in killing cancer cells through image-guided, photodynamic therapy (PDT) processes.

摘要： An article that includes a fluorescent composition having at least one of a fluorescent sensor compound and organic reporter molecules encapsulated in a microsphere structure. When encapsulated, the fluorescent sensor compound and the organic reporter molecules are distributed in a liquid organic matrix. When non-encapsulated, the remaining one of the fluorescent sensor compound and the organic reporter molecules reside in the matrix. In response to a force applied to the composition sufficient to break at least a portion of the microsphere structure, the fluorescent sensor compound and the organic reporter molecules are transformed into a non-reversible fluorescent state exhibiting a quantum yield greater than 0.2. The fluorescent state is objectively visually verifiable without physically contacting the composition.

摘要： Provided are a device with excellent operability and portability and a determination system that uses the device. The present disclosure relates to a device including a reagent portion in which a chemiluminescent indicator and a chemiluminescent substrate for the indicator are disposed, and a base on which the reagent portion is formed. The chemiluminescent indicator and the chemiluminescent substrate are disposed independently from each other in the reagent portion in such a manner that the chemiluminescent indicator and the chemiluminescent substrate can react with each other when a sample is supplied to the reagent portion. The present disclosure also relates to a remote diagnosis system including an imaging terminal for detecting a luminescent signal generated when a reagent is supplied to the device and an information processing unit for processing luminescent signal data obtained by the imaging terminal. The imaging terminal and the information processing unit can bi-directionally communicate with each other via a network.

摘要： A process of curing a photo-curable material includes dispersing a microcapsule in a material that includes a photo-initiator and a photo-curable material. The process also includes applying a stimulus to the microcapsule to trigger a chemiluminescent reaction within the microcapsule. The chemiluminescent reaction generating a photon having a wavelength within a particular emission range that is consistent with an absorption range of the photo-initiator. The photon exits the microcapsule to trigger the photo-initiator to initiate or catalyze curing of the photo-curable material.
