Abstract
: Ho(AcAc)3 modified ZnO quantum dots (QDs) were successfully prepared via a conventional method. The FTIR spectra were taken to explore the combination of Ho(AcAc)3 and ZnO QDs. The addition of Ho(AcAc)3 could lower the emission intensity of ZnO QDs by modifying the defects of ZnO QDs. Three types of ZnO QDs with different optical defects were used to composite with Ho(AcAc)3. The effect of Ho(AcAc)3 on different optical defects in ZnO QDs was distinctive. Ho(AcAc)3 modified ZnO QDs were successfully composited with the epoxy resin. With the addition of ZnO QDs, the emission intensity and UV absorption increased. Samples with Ho(AcAc)3 had higher visible light transmittance than those without Ho(AcAc)3. As such, Ho(AcAc)3 could improve the dispersity of ZnO QDs in epoxy. Thus, Ho(AcAc)3 could act as a compatibilizer between ZnO QDs and epoxy resin.
