Abstract

With the interest to study the structural, optical and spectroscopic properties of the molybdenum and calcium fluoride co-doped bismuth borate glasses added with small trace of chromium ions, a detailed investigation has been carried out. The samples with the formula xMoO₃-(20-x)CaF₂-20Bi₂O₃-59.8B₂O₃-0.2Cr₂O₃ were prepared by adopting melt-quench method. XRD, optical absorption, FTIR and Raman characterizations were studied for the glass samples and discussed elaborately. XRD reveals the amorphous nature of the prepared samples with broad hump. The density of the samples was calculated and reported an increase from 3.97 gm/cc to 4.203 gm/cc with increase in MoO₃ content. Similarly, the optical energy band gap also increase from 1.87 eV to 2.26 eV and is attributed to the decrease in NBO's. The refractive index of the glass samples in the range of 2.63–2.79 opens up applications in non-linear optical and opto-electronics devices. FTIR spectra in hand with Raman spectra provides evidence to the increase in compactness with increase in MoO₃ content, as there is a conversion of BO₃ to BO₄ units. The other probable structure units in the glass network include MoO^2-₄ and MoO₆ units resulting in structural stability.

利用物理、光学、拉曼和傅立叶变换红外特性深入分析 MoO3-CaF2-Bi2O3-B2O3-Cr2O3 玻璃体系

为了研究添加了微量铬离子的钼和氟化钙共掺杂硼酸铋玻璃的结构、光学和光谱特性，我们进行了详细的研究。采用熔融-淬火法制备了配方为 xMoO3-(20-x)CaF2-20Bi2O3-59.8B2O3-0.2Cr2O3 的样品。对玻璃样品的 XRD、光学吸收、傅立叶变换红外光谱和拉曼特性进行了研究和详细讨论。X 射线衍射显示制备的样品为无定形，具有宽驼峰。经计算，样品的密度随着 MoO3 含量的增加而从 3.97 gm/cc 增至 4.203 gm/cc。同样，光能带隙也从 1.87 eV 增加到 2.26 eV，这归因于 NBO 的减少。玻璃样品的折射率在 2.63-2.79 之间，这为其在非线性光学和光电子器件中的应用开辟了道路。傅立叶变换红外光谱和拉曼光谱证明，随着 MoO3 含量的增加，玻璃的致密性也会增加，因为其中的 BO3 单元会转化为 BO4 单元。玻璃网络中其他可能的结构单元包括 MoO2-4 和 MoO6 单元，从而提高了结构的稳定性。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
