| Outline of Final Research Achievements |
We proposed chemical fluid deposition (CFD) technique by using supercritical CO2 fluids and are establishing technique to enable to fill Gd materials into high-aspect ratio trench structures for neutron phase imaging. In this research, we try to develop the technique that impregnation of Gd2O3 nanocrystals into the trench to form nanocrystalline supralattice structures by synthesizing supercritical CO2 dispersed Gd2O3 nanocrystals. We deployed 3 step synthesis to obtain those supercritical CO2 dispersed Gd2O3 nanocrystals. First, Gd(III)oleate was synthesized in aqua and then, oleic-acid modified Gd2O3 nanocrystals was synthesized from Gd(III)oleate in Tri-n-octylamine by solvothermal method. Finally, hexafluoroacetylacetone(hfac) modified Gd2O3 nanocrsytals that can be dispersed in supercritical CO2 were obtained by using ligand exchange. Currently, we are developing CFD method that enables to deposit the nanocrystals by decreasing dispersibility with local cooling on substrates.
