Spontaneous growth of polarizing refractory metal 'nano-fins'.

摘要: Traditional polymer polarizers degrade in harsh environments and at high temperatures, reducing the polarization effect. In contrast, produced with refractory metals have vastly improved thermal stability resistance to but are expensive fabricate. Here we demonstrate prototype metal wire grid by co-sputtering molybdenum aluminum under specific conditions. Removal of through selective dissolution enables nanostructure array transmit light. The spans 500-1100 nm extinction ratio significantly increases >100. Possessing broadband sufficient ratios, new polarizing film has potential applications coatings for sunglasses, windows, pyrometers, scientific instruments, LCD panels.
