Abstract

In the present study, newly synthesized nitrobenzene derivatives (PBT and PBF) doped poly(methyl methacrylate) films were prepared using spin coating techniques, and their optical properties were analyzed. The absorption spectra of various weight percentages (0.02%, 0.1%, 0.2%, and 0.3%) of nitrobenzene derivative-doped polymer films were recorded using a UV–visible spectrometer. From the absorption spectra, optical properties such as refractive index, band gap energy, extinction coefficient, and dielectric constant were calculated. The effect of doping on the optical properties of PMMA was investigated, with results revealing normal dispersive behavior from the refractive index and extinction coefficient. Atomic force microscopy and scanning electron microscopy images indicated that the synthesized films have a low degree of roughness and a smooth surface. Additionally, the nonlinear optical properties of the PBF-doped polymer film were investigated, and the β value was determined to be 7.403 cm/W. Overall, the findings suggest that PBF-doped polymer films are promising candidates for photonic applications.

用于光子应用的掺杂恶二唑类似物 PMMA 薄膜的光学表征
本研究采用旋涂技术制备了新合成的掺杂硝基苯衍生物(PBT 和 PBF)的聚甲基丙烯酸甲酯薄膜,并分析了它们的光学特性。使用紫外可见光谱仪记录了不同重量百分比(0.02%、0.1%、0.2% 和 0.3%)的掺杂硝基苯衍生物聚合物薄膜的吸收光谱。根据吸收光谱计算出折射率、带隙能、消光系数和介电常数等光学特性。研究了掺杂对 PMMA 光学特性的影响,结果显示折射率和消光系数具有正常色散行为。原子力显微镜和扫描电子显微镜图像显示,合成的薄膜粗糙度低,表面光滑。此外,还研究了掺杂 PBF 的聚合物薄膜的非线性光学特性,并确定其 β 值为 7.403 cm/W。总之,研究结果表明,掺杂 PBF 的聚合物薄膜在光子应用领域大有可为。
