| 中文摘要 | beta-nayf4 microcrystals with a variety of morphologies, such as microrod, hexagonal microprism, and octadecahedron, have been synthesized via a facile hydrothermal route. x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), high-resolution transmission electron microscopy (hrtem), and photoluminescence (pl) spectra were used to characterize the samples. the intrinsic structural feature of beta-nayf4 seeds and two important external factors, namely, the ph values in the initial reaction solution and fluoride sources, are responsible for shape determination of beta-nayf4 microcrystals. it is found that the organic additive trisodium citrate (cit(3-)) as a shape modifier has the dynamic effect by adjusting the growth rate of different facets under different experimental conditions, resulting in the formation of the anisotropic geometries of various beta-nayf4 microcrystals. the possible formation mechanisms for products with various architectures have been presented. a systematic study on the photoluminescence of tb3+-doped beta-nayf4 samples with rod, prism, and octadecahedral shapes has shown that the optical properties of these phosphors are strongly dependent on their morphologies and sizes. |
