Abstract

Sphere- and rod-shaped Zn(2)SiO(4):Mn(2+) phosphor nanocrystals were synthesized at 230 degrees C. The process consists of tuning the surfactant concentration in the oil/surfactant/ethanol system. Powder X-ray (XRD) and transmission electron microscopy (TEM) were used to characterize the phase purity, size and morphology. Photoluminescent (PL) spectra were collected and analyzed. Fourier transform infrared (FT-IR) spectra of the samples indicate the removal of surfactant in the phosphor nanoparticles. As a result, the sphere-shaped phosphor nanoparticles of 100 nm in size can be redispersed in ethanol ultrasonically. The suspension maintain stable for over 48 h.

摘要

在230摄氏度下合成了球形和棒状的Zn(2)SiO(4):Mn(2+)荧光粉纳米晶体。该过程包括调节油/表面活性剂/乙醇体系中的表面活性剂浓度。使用粉末X射线（XRD）和透射电子显微镜（TEM）来表征相纯度、尺寸和形态。收集并分析了光致发光（PL）光谱。样品的傅里叶变换红外（FT-IR）光谱表明荧光粉纳米颗粒中的表面活性剂已被去除。结果，尺寸为100nm的球形荧光粉纳米颗粒可以通过超声在乙醇中重新分散。该悬浮液保持稳定超过48小时。
