Abstract

This work shows a correlation between light reflectance, absorption, and morphologies of series of (1-x) BM–x PT, (x = 0.0, 0.02, 0.04, 0.08, 0.12, 0.16, 0.24) ceramics composite. The (1-x) BM–x PT showed features of a black mirror with a low optical energy gap. The measured Vis-NIR diffused reflectance enabled the calculation of the energy gap using the modified Kubelka-Munk function. The estimated energy gap was lower than 1.5 eV related to low reflectance in the Vis-NIR range. Moreover, obtained histograms of grains, using scanning electron microscope, enabled the correlation between grains size and amount of lead titanate. We deduced from the ceramics surface morphology that marked porosity also induced reflectivity of low magnitude. We correlated the magnitude of the energy gap with phases of the BM-PT composite and with the electrical conductivity activation energy reported in the literature. Our results findings opened prospect studied materials for optical applications.

锰酸铋-钛酸铅无序陶瓷的可见光和近红外漫反射研究
这项工作显示了一系列(1-x) BM-x PT, (x = 0.0, 0.02, 0.04, 0.08, 0.12, 0.16, 0.24)陶瓷复合材料的光反射率,吸收率和形貌之间的相关性。(1-x) BM-x PT具有低光能隙的黑镜特征。测量的可见光-近红外漫反射系数使得利用改进的Kubelka-Munk函数计算能隙成为可能。估计的能隙小于1.5 eV,这与可见光-近红外范围内的低反射率有关。利用扫描电镜获得晶粒直方图,实现了晶粒尺寸与钛酸铅用量之间的相关性。我们从陶瓷表面形貌推断,孔隙率显著的陶瓷也会引起低量级的反射率。我们将能隙的大小与BM-PT复合材料的相以及文献中报道的电导率活化能联系起来。我们的研究结果为光学材料的应用开辟了广阔的前景。
