Synthesis and morphology control of YBO3:Tb3+ green phosphor by precipitation from homogeneous solution

Cubic shaped YBO3:Tb3+ green phosphor was synthesized by precipitation from homogeneous solution. Prepared precipitates were identified as Y[B(OH)4](CO3) by X-ray diffraction, and cubic shaped particles of about 2 µm were observed by a scanning electron microscope. By heating at 800°C, the cubic sha...

Zusammenfassung:Cubic shaped YBO3:Tb3+ green phosphor was synthesized by precipitation from homogeneous solution. Prepared precipitates were identified as Y[B(OH)4](CO3) by X-ray diffraction, and cubic shaped particles of about 2 µm were observed by a scanning electron microscope. By heating at 800°C, the cubic shape of the particles was kept and YBO3 was obtained. Tb-doped YBO3 samples which were controlled as cubic shaped particles showed bright green emission by UV excitation.
