Abstract

In the present work, NaBi(MoO4)2 (NBM) phosphor has been successfully synthesized by doping 1.0 mol% of Eu3+ via the conventional solid state reaction technique. The undoped synthesized NBM sample and 1.0 mol% Eu3+ doped phosphor were characterized to explore crystal structure, morphology, photoluminescence (PL) and colorimetric properties using various characterization techniques. The structural properties were analysed via x-ray diffraction and diffraction peaks were compared with the standard JCPDS (card no. 79-2240) pattern. The morphological studies of the sample have been done through FE-SEM micrograph. From the photoluminescence emission spectra, it has been observed that an intense peak was obtained in the at 615 nm under blue excitation. Colorimetric property of 1.0 mol% of Eu3+ doped NBM phosphor has been investigated and traced in the red region with high color purity of 92.79%. The aforementioned characteristics demonstrate that the NaBi(MoO4)2: 1.0Eu3+ phosphor has great potential in the field of w-LED applications.

研究用于 W-LED 应用的 Eu3+ 活化钼酸盐基荧光粉的结构、形态和发光特性

在本研究中，通过传统的固态反应技术，成功合成了掺杂 1.0 mol% Eu3+ 的 NaBi(MoO4)2 (NBM) 荧光粉。利用各种表征技术对未掺杂合成的 NBM 样品和掺杂 1.0 mol% Eu3+ 的荧光粉进行了表征，以探索其晶体结构、形貌、光致发光 (PL) 和比色特性。通过 X 射线衍射分析了结构特性，并将衍射峰与标准 JCPDS（卡号 79-2240）图案进行了比较。样品的形态研究是通过 FE-SEM 显微照片完成的。从光致发光发射光谱中可以观察到，在蓝色激发下，在 615 纳米波长处出现了一个强烈的峰值。对掺杂了 1.0 mol% Eu3+ 的 NBM 荧光粉的色度特性进行了研究，结果显示其红色区域的色度纯度高达 92.79%。上述特性表明，NaBi(MoO4)2: 1.0Eu3+ 荧光粉在 w-LED 应用领域具有巨大的潜力。
