Zinc oxide levels in cosmetic formulations are commonly analyzed by atomic absorption (AA) spectroscopy using the fusion method for sample digestion, a labor-intensive and time-consuming process that causes lengthy delays in product manufacturing.
Dispersion of surface polaritons in zinc phosphide (Zn3P2) single crystals is presented in this article for the first time. Surface polaritons in Zn3P2 were excited using the attenuated total reflectance (ATR) method.
