Abstract:
The organic-inorganic luminescent hybrid mesoporous materials (LHMS) was prepared via aminopropyl groups modification and subsequently 1,8-Naphthalic anhydride loading by using bimodal mesoporous materials (BMMs) and MCM-41 as carriers, respectively. The resultant hybrid materials were characterized by XRD, TEM, SEM, BET, FT-IR and PL methods. It was showed that the emission peak position of LHMS-BMMs is around 444 nm, while for LHMS-MCM-41 with about 450 nm, demonstrating that the blue-shift phenomenon of LHMS-BMMs was more remarkable than that of LHMS-MCM-41. The most reason is the different morphology and related particle sizes between BMMs and MCM-41:BMMs is of spherical particle with a size of around 50 nm and uniform mesopores (about 3 nm), while MCM-41 reveals irregular particle distribution in the range of 1-3 μm, but with uniform one-dimensional mesopores (about 3 nm).
