掺锶量对羟基磷灰石形貌及其荧光特性的影响
Influence of Strontium on Hydroxyapatite Morphology and Luminescence Characteristics
摘要
Abstract
Strontium Hydroxyapatite (SrxCa10-x(PO4)6(OH)2, x=0, 3, 5, 10) powder with fluorescence property was successfully synthesized by a facile hydrothermal process. X-ray diffraction, Fourier transform infrared spectros-copy, X-ray photoelectron spectra, field emission scanning electron microscope and photoluminescence excitation and emission spectra were employed to analyze phase change, characteristics and fluorescence property of samples. The experimental results indicate that the morphology of samples is spherical particle(D=1～2 μm), and with the amount of strontium changed from 0 to 100mol%, the morphology of spherical particle changes from short nano-rods to nanosheets and then long nanorods. The samples show an intense and bright blue emission from 375 nm to 500 nm centered at 432 nm under long-wavelength UV light excitation (351 nm). The PL emission intensity firstly increases and then decreases with increasing the strontium content. When strontium content is 30%, the PL emission intensity reaches the maximum.关键词
