The influence of polymer environment
on the luminescent properties of barium zirconate nanocrystals has been studied by cathodoluminescence
(CL) spectroscopy. It was found that a polystyrene (PS) shell around the BaZrO3
nanocrystals significantly modifies the CL spectra. This phenomenon can be explained by
interaction between the PS matrix and the BaZrO3 particles, changing
the surface states of the nanocrystals. This
conclusion is confirmed by complementary experimental studies including X-ray
diffraction, FTIR spectroscopy and scanning electron
microscopy.
