| 英文摘要 | the morphology, size and phase control of luminescent fluoride nanocrystals through doping has become a new research hotspot due to their improved properties. in this work, yb3+ ions, as one of the most efficient sensitizers for various lanthanide activators, were doped in nagd(y)f-4 nanocrystals. the results show that no obvious influence was observed for yb3+-doped nayf4 nanocrystals, while the influence of yb3+ doping on nagdf4 nanocrystals was remarkable. the nagd1-xybxf4 nanocrystals were synthesized by a hydrothermal route and had a morphology of rice-like nanorods. by controlling the synthesis parameters, the average size and slenderness of the nanocrystals increased gradually with addition of yb3+ ions. in contrast, the nagd1-xybxf4 nanocrystals maintained a hexagonal phase, which is more beneficial for application as a luminescent host, until the content of yb3+ ions reached x = 0.9. the growth and transformation mechanism of nagd1-xybxf4 nanocrystals was proposed to be a result of the competition between ion diffusion and an oswald ripening process. photoluminescence (pl) spectra confirm the efficient up-conversion and near-infrared (nir) two-model luminescence properties of er3+ (tm3+) activated nagd(y)(1-x)ybxf4 nanocrystals. simulated analysis results indicate that a colloidal solution of mixed luminescent nanocrystals is expected to find application as the activated medium of three dimensional displays and a broadband optical amplifier. |
