Abstract

Silver and gold nanostructures were fabricated by thermal deposition followed by laser annealing on novel type substrates - diamond abrasive films and scratched quartz plates. The morphology and optical properties of the nanostructures were studied and they were applied for surface-enhanced Raman spectroscopy of the insecticide Karate Zeon 5 CS (lambda-cyhalothrin). The limit of detection of about ≈50 µM was estimated. Advanced substrates for surface-enhanced Raman spectroscopy of pesticides were developed. For this purpose alumina, quartz, paper, and diamond abrasive films substrates were used on which silver and gold nanostructures were produced using pulsed laser, ion-beam or thermal deposition, and laser annealing. The effectiveness of these active substrates for detecting several pesticides was evaluated and discussed.

用于农药表面增强拉曼光谱的高级银和金底物

摘要

银和金纳米结构是通过热沉积制造的,然后在新型基材上进行激光退火 - 金刚石磨料膜和划痕石英板。研究了纳米结构的形态和光学特性,并将它们应用于杀虫剂 Karate Zeon 5 CS(λ-三氯氟氰菊酯)的表面增强拉曼光谱。估计检测限约为 ≈50 µM。开发了用于农药表面增强拉曼光谱的先进底物。为此目的,使用氧化铝、石英、纸和金刚石研磨膜基材,在其上使用脉冲激光、离子束或热沉积和激光退火生产银和金纳米结构。评估和讨论了这些活性底物检测几种农药的有效性。
