| dc.description.abstract | Tm3+-doped Y2O3 nanocrystals were prepared via hydrothermal conditions at high autogenous pressure (ca 40 MPa) using batch reactors at 220 and 250 degrees C for very short periods of reaction time (10 min). The as-prepared materials were identified as Y(OH)(3) nanoparticles The precursor materials with two types of morphologies, such as sphere and rod-shaped particles were prepared at 220 and 250 degrees C within 10 min. The sizes of the as-prepared sphere particles are 1015 nil. in diameter, whereas the rod-shaped particles show 15-20 nm in diameter and 0.1-0.2 mu m to lengths The precursor materials were calcined at 500 and 800 degrees C for 5 h in air to obtain (3 mol-%) Tm3+-doped Y2O3 nanocrystals For the characterization, KRD, FESEM, EDS and TG-DTA were employed. The photoluminescence spectra of sphere and rod-shaped particles show higher blue emission at 450 nm than the reference sample. | |
