Technology Innovation in the Nanoparticle Project

Abstract

The five-year METI/ NEDO's nanoparticle project started in 2001. In this study, various nanosized particles, e.g. Au, Ag, GaN, ZnO, FePt, CdSe, Y2O3:Eu, (Y,Gd)

Liquid-phase Synthesis of CaF₂ Particles and Their Low Refractive Index Characterization

“…Besides, we also successfully developed a process for the synthesis of particles with controllable size and morphology using a spray method. [11][12][13][14][15][16][17][18][19][20][21][22][23][24] Here, we report the synthesis of CaF2 particles with controllable size and morphology using the liquidphase synthesis method. Different from other CaF2 synthesis methods, the synthesis was based on the reaction of Ca 2 and F ions in an aqueous solution in the absence of additional components (polymers, surfactants, chemicals, etc.).…”
