SYNTHESIS AND CHARACTERIZATION OF GADOLINIUM COLLOIDS IN 2-METHOXYETHANOL
Gadolinium colloids have been prepared by Chemical Liquid Deposition (CLD). The metal is cocondensed with 2-methoxyethanol to yield solvated metal atoms at liquid nitrogen temperature and upon warming stable liquid colloids are formed with several ranges of particle size depending on the amount of m...
