Au nanoparticle (NP) substrates, Au NP/TiO(2)/Au NP sandwich structures, and Ti coated Au NP substrates are fabricated by glancing angle deposition (GLAD) and oblique angle deposition (OAD) methods. Under the same deposition condition, the Au NP substrates produced by GLAD are more uniform and reproducible compared to those fabricated by OAD. The localized surface plasmon resonance (LSPR) wavelength of Au NP substrates can be easily tuned by changing the film thickness, the deposition angle, and the coating of the dielectric layer (TiO(2)) and metallic layer (Ti). In addition, the thickness and the deposition angle of the Ti coating on Au NP also affect the LSPR wavelength. Our results demonstrate that GLAD is a very versatile fabrication technique to produce reproducible and fine-tuned LSPR substrates.
采用掠角沉积（GLAD）和斜角沉积（OAD）方法制备了金纳米粒子（NP）衬底、金 NP/TiO(2)/金 NP 三明治结构和涂钛金 NP 衬底。在相同的沉积条件下，与 OAD 制备的金 NP 衬底相比，GLAD 制备的金 NP 衬底更加均匀和可重复。通过改变薄膜厚度、沉积角度以及电介质层（TiO(2)）和金属层（Ti）的涂层，可以轻松调节金 NP 衬底的局域表面等离子体共振（LSPR）波长。此外，涂钛金 NP 的厚度和沉积角度也会影响 LSPR 波长。我们的结果表明，GLAD 是一种非常通用的制造技术，可以制备出可重复且精细调整的 LSPR 衬底。
