摘要

摘要采用改进的两步固态扩散法制备了basi6n80:Eu3+荧光粉，并将材料在1200℃下淬火4小时。用XRD对Eu3+活化的basi6n80o荧光体进行了表征，证实了样品的形成。从扫描电子显微镜(SEM)图像，研究了样品的表面形貌。basi6n80:Eu3+荧光粉在激发波长为396 nm的614 nm (5D0→7F2)和587 nm (5D0→7F1)处有两个发光带。从FTIR光谱中，研究了原子之间的键合和分子的振动运动。通过在辐照样品上滴下活塞来研究ML。从ML发光曲线中观察到单峰。ML强度随活化剂浓度的增加而增加。对含有1mol % Eu离子的样品，观察到最佳ML值。

Luminescence studies on BaSi6N8O: Eu3+ phosphors

ABSTRACT This paper reports on the BaSi6N8O:Eu3+ phosphor were prepared via modified two steps solid state diffusion technique in open air atmosphere and material was quenched at 1200°C for four hours. Eu3+ activated BaSi6N8O phosphor was characterized by XRD, which confirms the formation of the sample. From the Scanning electron microscope (SEM) images, the surface morphology of the sample has been studied. The photoluminescence (PL) spectra of BaSi6N8O:Eu3+ phosphor exhibits two emission bands at 614 nm (5D0→7F2) and at 587 nm (5D0→7F1) with an excitation wavelength of 396 nm. From the FTIR spectrum, bonding of atoms to each other and vibrational motions of molecules has been studied. ML was studied by dropping a piston on irradiated sample. From the ML glow curves single peak has been observed. ML intensity increases with activator concentration. Optimum ML has been observed for the sample having 1mole % of Eu ions.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
