Abstract

A method of preparing a dye-functionalized flexible upconversion-luminescence solid-phase sensor, including: preparation of upconversion-luminescence nanoparticles, preparation of an upconversion nanoparticle-doped solid-phase sensor, and preparation of a dye-functionalized flexible upconversion-luminescence solid-phase sensor. A method for detecting a gaseous pollutant is also provided, including: preparing a dye-functionalized flexible upconversion-luminescence solid-phase sensor through the above method; establishing a prediction model; and substituting a fluorescence intensity of a sample into the prediction model to calculate the gaseous pollutant concentration in the sample.
