Synthesis of (Sr, Eu)CO3@SiO2 core-shell-like precursor for alkali earth silicate phosphors
چکیده انگلیسی

Monodisperse (Sr, Eu)CO3 sphere (the homogenous mixture of Sr2+ and Eu3+ carbonates) was firstly prepared, and then its surface was coated by amorphous SiO2 in the presence of cationic surfactant cetyltrimethylammonium bromide (CTAB) to form (Sr, Eu)CO3@SiO2 core-shell-like precursor. The overall synthesized mechanism was investigated and proposed based on the Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). This strategy could be applied to construct core-shell structured precursors for the preparation of alkali earth silicate phosphors.
