Photophysical Characterization of Er3+ doped and Er3+/Nd3+ co-doped Gd(OH)3 Nanocrystals: the Impact of Hexamethylenetetramine utilization for Morphology Engineering

“…The entire IR absorption spectra can be sorted by separating into three regions; Firstly, the 4000-3000 cm -1 region with intense broad absorption band. Secondly, the occurrence of weak bands coupled with few narrow bands in the region of 3000 to 1800 cm -1 and lastly, the region between 1800 to 500 cm -1 that contained multiple sharp weak bands [43]. All spectra displayed a very sharp but weak peak at 3609 cm −1 corresponds to Gd-O-H stretching vibration [44], and a strong and broad peak around 3399 cm -1 which indicate the presence of high concentration of hydroxyl (OH -) groups of Gd(OH)3 in the 4000-3000 cm -1 region [45].…”
