Single use cetyl trimethyl ammonium bromide (CTAB) surfactant coating dye and transferred to water by sol - gel method with fluorescent dye as the core, the mesoporous silicon dioxide nanoparticles (MSNs of) fluorescence shell mesoporous silica nanoparticles. The effects of the use of DLS TEOS, surfactants, ammonia, dye concentration on the particle size, the use of SEM, TEM, TG, UV, PL spectroscopy by means of composite nanoparticles structure, morphology, thermal stability spectra were characterized and discussed. 

The results show that with the increase of the amount of TEOS and ammonia, particle size increases; when less amount of surfactant particle size will be larger; low dye concentration on the particle size was less affected; powder preparation out It can be controlled at about 100nm; fluorescence intensity increase, and the dye-doped silica optimal mass ratio of 1.5 × 10-3; because it is physically coated so limited thermal stability, UV resistance, aging resistance significantly improved.

Uniform Design mesoporous carbon nano and nano-mesoporous silica complex, four-ball friction tester for complex formulation tribological properties were tested. It was found that complex system is able to improve the antiwear properties of the lubricating oil; complex system Mesoporous carbon and mesoporous silicon dioxide can play to their respective advantages, namely to improve the extreme pressure properties of lubricants and anti-friction properties.
