摘      要：A facile green low-cost controllable hydrothermal-thermal conversion(HTC) process for the uniform high aspect ratio CaSiO_3 nanowires has been developed using abundant CaCl_2·2H_2O and Na_2 SiO_3·9H_2O as raw materials without any organic additive. The nanowires exhibited a transparent characteristic from the ultraviolet to visible region, and the CaSiO_3:1.2%Tb^(3+)nanophosphors with well preserved 1D morphology demonstrated strong green luminescence with CIE coordinates of(x=0.3144, y=0.5912).The present work definitely reveals the nanowires as a promising structure and function integrated host candidate for green-emitting luminescent materials in light display systems and optoelectronic devices.
