ENGINEERING THE NaYF4:Yb3+/Tm3+ UPCONVERSION NANOPARTICLE LUMINESCENCE ENERGY TRANSFER FOR A RATIOMETRIC pH INDICATOR

Fluorescent dye 8-hydroxypyrene-1,3,6-trisulfonic acid (HPTS) is used to develop a ratiometric pH indicator based on NaYF4:Yb3+/Tm3+ upconversion nanoparticles (UCNPs). HPTS was functionalized onto the UCNP surfaces via a modified co-condensation silica coating (UCNP@SiO2-HPTS). The as-prepared UCNP...
