AB  - Multifunctional sensing, a strategy to improve the efficiency of analysis and 
      detection, has attracted much attention. In this study, a multifunction sensing 
      platform was developed for temperature, pH, and proton pump inhibitors (PPI) with 
      fluorescence carbon dots. Solvent-dependent carbon dots (PG-CDs) were synthesized 
      through a one-step solvothermal method from phloroglucinol with the assistance of 
      HCl. Base on the effect of functional groups on the surface, solvent-dependent 
      behavior, temperature and pH responsive fluorescence can be observed. The PG-CDs 
      display a reversible temperature-sensitive fluorescent behavior within 15-65  degrees C 
      in N, N-dimethylacetamide. The fluorescence intensity of PG-CDs also responded to 
      pH in a range of 3.0-7.0 with good reversibility and anti-interference. 
      Therefore, the platform for temperature and pH sensing was proposed. In addition, 
      since the synergistic effect of dynamic and static quenching, proton pump 
      inhibitors (PPI) can be detected sensitively, including esomeprazole (EPZ), 
      omeprazole (OPZ), and rabeprazole (RPZ). The linear range of detection for EPZ, 
      OPZ, and RPZ is 2.0-80.0, 2.0-75.0, and 10.0-200.0 muM and the limits of detection 
      is 0.29, 0.55, and 2.99 muM, separately. The recoveries for real samples were 
      between 91.83 and 102.3%, which indicated that the platform for PPI sensing had 
      good accuracy.
