摘要

采用共沉淀法合成了锰、钴原子掺杂的氧化锡。利用x射线衍射（XRD）和透射电镜（TEM）分析了其结构特征。利用紫外-可见光谱和光致发光光谱对其光学特性进行了研究。利用场发射扫描电镜（FESEM）研究了其形态特性，利用紫外-可见和光致发光光谱技术研究了其光学特性，并利用能量色散x射线（EDX）分析确定了其元素特性。锰和钴的掺入使SnO2结晶度下降。Tauc图显示带隙明显缩小。形貌和元素分析表明，制备的样品存在一定的团聚现象。样品在日光下表现出良好的光催化性能，降解率达96.08%。

Degradation of crystallinity in tin oxide incorporated with manganese and cobalt synthesized using co-precipitation method

Tin oxide (SnO₂) incorporated with manganese and cobalt atoms has been synthesized using co-precipitation route. Structural characteristics were estimated using X-ray diffraction (XRD) and Transmission electron microscopy (TEM). Optical characteristics were investigated using UV–Visible and Photoluminescence spectroscopy. Morphological properties were investigated using Field emission scanning electron microscopy (FESEM), optical characteristics were investigated using UV–Visible and Photoluminescence spectroscopic techniques, and elemental characteristics were confirmed by using Energy Dispersive X-Ray (EDX) analysis. Incorporation of manganese and cobalt in SnO₂, degraded the crystallinity. Band gap narrowing was evident from Tauc plot. The morphological and elemental analysis indicated that prepared sample has some agglomeration. The sample showcased good photocatalytic properties under sunlight and degraded rose bengal dye up to 96.08 %.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
