摘要: A series of Eu3+ doped manganese phosphite (JIS-10:Eu3+) red phosphors was prepared via the hydrothermal method. The regulation of Eu3+ doping concentration on the material structure, luminescence properties, and antibiotic fluorescence sensing characteristics was systematically investigated. Experiments showed that when the Eu3+ doping concentration (molar fraction) was 0.01, the material exhibited the strongest red emission at 617 nm. Under near-ultraviolet excitation at 394 nm, the luminescence intensity of JIS-10:0.01Eu3+ showed a linear relationship with the Eu3+ concentration. When this material was used as a fluorescent probe for tetracycline detection, its fluorescence intensity exhibited a good linear response to tetracycline concentration in the range of 0.1—200 μmol/L, and it showed significant selectivity towards structural analogs, such as sulfadiazine and norfloxacin.
