Merocyanines adsorbed into the mesopores of mSiO2 shell of NaYF4: 20% Yb, 2% Er, 0.2% Tm nanocrystals are demonstrated as ratiometric upconversion luminescence (UCL) probe for highly selective detection of HS(-) in living cells through inhibition of energy transfer from the UCL of the nanocrystals to the absorbance of the merocyanines. The UCL probe has been used for ratiometric sensing of H2S with high sensitivity and selectivity.
将甲川花菁染料吸附到 NaYF4:20%Yb,2%Er,0.2%Tm 纳米晶的介孔 mSiO2 壳中，通过抑制纳米晶上的上转换发光（UCL）到甲川花菁染料的吸收的能量转移，该染料被证明是一种用于活细胞中 HS(-) 高选择性检测的比率型上转换发光（UCL）探针。该 UCL 探针已用于 H2S 的比率型传感，具有高灵敏度和选择性。
