AB  - A ratio fluorescence nanoprobe was constructed by simple mixing BCNO QDs with 
      8-hydroxyquinoline-5-sulfonic acid (HQSA), which had an obvious fluorescence peak 
      at 420 nm and a weak fluorescence peak at 500 nm, corresponding to the BCNO QDs 
      and HQSA, respectively. This fluorescence probe takes stable fluorescence of BCNO 
      QDs as an internal standard, based on HQSA chelating enhanced fluorescence and 
      specificity of phosphate in the presence of Mg(2+), which realizes a rapid and 
      sensitive detection of phosphate with good linearity in the range 0.3-50 muM and 
      50-100 muM and a detection limit of 0.073 muM. The recovery is between 94.1 and 
      111% and the relative standard deviations (RSDs) below 10%. At the same time, we 
      took color photos of the reaction solution under 310-nm UV lamp with smartphones 
      for visual detection through RGB data image analysis, which make the detection 
      easier and faster. The proposed method provides a new strategy for the 
      intelligent online detection of other targets in complex environment samples.
