Embodiment 1
[0037] With 7.28g cetyltrimethylammonium bromide, 500ml organic solvent (V / V trichloromethane: isooctane=1:1), 25 ℃ 5ml lanthanum chloride saturated aqueous solution (3.89mol / L), 6.049 g of isopropyloctyldecylamine was added to a four-neck flask with temperature control and stirring to dissolve the solid, and concentrated hydrochloric acid was added dropwise to make the mixture clear and transparent. Pass a certain amount of hydrogen fluoride gas into the microemulsion at 25°C until the mixture turns blue. Evaporate under reduced pressure at 30°C for 24 hours to obtain a light yellow viscous liquid, to which 650ml of tetrahydrofuran was added and stirred, and the insoluble matter was filtered off. Finally, tetrahydrofuran was evaporated under reduced pressure to obtain 5.13 g of a yellow substance, that is, lanthanum fluoride nanoparticles coated with nitrogen-containing organic matter were prepared.
Embodiment 2
[0039] With 273g cetyltrimethylammonium bromide, 5000ml organic solvent (V / V chloroform: normal hexane = 1: 1), 25 ℃ 5ml lanthanum chloride saturated aqueous solution (3.89mol / L), 14.199g tert-butylamine , adding to a four-neck flask with temperature control and stirring for mixing to dissolve the solid, and adding concentrated hydrochloric acid dropwise to make the mixture clear and transparent. A sufficient amount of hydrogen fluoride gas was passed through the microemulsion until the mixture turned blue. Evaporate under reduced pressure at 30°C for 24 hours to obtain a light yellow viscous liquid, to which 500ml tetrahydrofuran was added and stirred, and the insoluble matter was filtered off. Finally, tetrahydrofuran was evaporated under reduced pressure to obtain 4.73 g of a yellow substance, that is, lanthanum fluoride nanoparticles coated with nitrogen-containing organic matter were prepared.
Embodiment 3
[0041] With 21.84g cetyltrimethylammonium bromide, 600ml organic solvent (V / V chloroform: isooctane=1: 1), 20.946g ashless dispersant T154 (produced by Jinzhou Petrochemical Company, nitrogen content 1.3%) wt), 5ml of lanthanum chloride saturated aqueous solution (3.89mol / L) at 25°C was added into a four-neck flask with temperature control and stirring to dissolve the solid, and concentrated hydrochloric acid was added dropwise to make the mixture clear and transparent. A sufficient amount of hydrogen fluoride gas was passed through the microemulsion until the mixture turned blue. Evaporate under reduced pressure at 30°C for 24 h to obtain a black viscous liquid, to which 300 ml of tetrahydrofuran was added and stirred, and the insoluble matter was filtered off. Finally, tetrahydrofuran was evaporated under reduced pressure to obtain 5.24 g of black matter, that is, lanthanum fluoride nanoparticles coated with nitrogen-containing organic matter were prepared.
