The interfacial effect is one of the significant factors in the glass-transition temperature (T<sub>g</sub>) of the polymeric thin film system, competing against the free surface effect. Herein, the T<sub>g</sub>s of poly (methyl methacrylate) (PMMA) films with different thicknesses and substrates are studied by fluorescence measurements, focusing on the influence of interfacial effects on the T<sub>g</sub>s. The strong interaction between PMMA and quartz substrate leads to increased T<sub>g</su ...[more]
