Terbium and barium codoped mesoporous silica nanoparticles with enhanced optical properties
نویسندگان
چکیده
In this study, we showed for the first time that barium (Ba) codoping improves luminescent properties of terbium (Tb)-doped SiO2 nanoparticles (NPs). particular, quantum yield (QY) SiO2-Ba,Tb NPs was found to be ∼10.7%, whereas QY bare SiO2-Tb only ∼4.3%. Several mechanisms luminescence enhancement have been proposed. We strongly believe methodology can used create alternative silica-based with improved optical characteristics.

In this study, a novel mesoporous silica nanoparticles drug carrier contributes to improving the solubility, dissolution, and the oral bioavailability of apigenin (AP). The apigenin of solid dispersion of mesoporous silica nanoparticles (AP-MSN) was prepared by physical absorption method and also, in-vitro drug release and in-vivo bioavailability performance were evaluated. Based on its solubil...

متن کاملUltrabright fluorescent mesoporous silica nanoparticles.
The first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles is reported. Fluorescent dye is physically entrapped inside nanochannels of a silica matrix created during templated sol-gel self-assembly. The problem of dye leakage from open channels is solved by incorporation of hydrophobic groups in the silica matrix. This makes the approach compatible wit...
متن کاملOptical properties of ordered mesoporous layers of silica
Mesoporous layers of silica are of interest for many optical applications, including the creation of devices ranging from optical sensors to laser sources with promising characteristics. Their optical characterization goes through the interpretation of measurements. We propose to give experimental results of reflectance and scattering measurements concerning mesoporous layers of silica deposite...
