摘要

本文介绍了用激光诱导击穿光谱(LIBS)分析紫外线照射下牙齿纳米复合修复材料。材料样品使用3M ESPE Elipar FreeLight2光源进行紫外线照射。利用调q Nd: YAG激光器的基束，结合配备Andor iStar ICCD相机的MS257光谱仪(Oriel仪器)记录样品的LIBS光谱。这些样品的发射光谱已被记录为激光辐照度的函数。在这些样品中检测到微量的钛、硅、铝、锶、锆、钠和钙。发现元素组成非常相似，但Zr和Si的相对丰度在更多的紫外线照射材料中更高。并用SEM - EDS对样品进行了对比分析。

Qualitative analysis of dental nano-composite restorative material using laser induced breakdown spectroscopy and EDS analysis

We have presented Analysis of UV irradiated dental nanocomposites restorative materials using laser-induced breakdown spectroscopy (LIBS). Samples of the materials are irradiated with UV light using 3M ESPE Elipar FreeLight2 Source. LIBS spectra of the samples are recorded using fundamental beam from Q-Switched Nd: YAG laser in conjunction with MS257 Spectrograph (Oriel instrument) equipped with Andor iStar ICCD camera. The emission spectra of these samples have been recorded as a function of laser irradiance. Traces of Titanium, Silicon, Aluminum, Strontium, Zirconium, Sodium and Calcium are detected in these samples. The elemental composition is found to be quite similar but the relative abundance of Zr and Si is higher in more UV exposed material. The samples have also been analyzed with SEM EDS for comparison.
