    Abstract
    Lanthanide nanoborates ) were prepared in the presence of polyethylene glycol using a buffered-precipitation method. The same procedure was performed without adding PEG to expose the chemical formulations of the samples. X-ray diffraction , thermal gravimetric analysis , Fourier transform infrared spectrum strongly supported amorphous lanthanide orthoborates having LnBO 3 ·3H 2 O structure. From TEM images, the mean particle size and standard deviation for Dy and Tb were calculated as 15.2 ± 6.3 nm and 15.4 ± 6.1 nm, respectively. The percentages of PEG molecules in the samples...
