Theoretical study of a pure LinbO3/Quartz waveguide coated gold nanorods using supercontinuum laser source

A sight of view on electrical impacts, structural properties and surface roughness of tungsten trioxide thin film: effect of substrate temperatures in WO3/Si device fabrication

“…This might be caused by variations in the inter planar spacing of the films as well as defects in the WO 3 lattice sites at higher substrate temperatures. Also, with thinner films, the strain and the dislocation density are found to be raised too [36,37], indicating an inverse relationship between grain size, strain, and dislocation density as shown in table 2 [38][39][40][41][42].…”

Fiber Optics for Sensing Applications in a Review

“…We can see from the above comparison between nine previous works which employed AuNPs in the development of diverse types of optical Biosensors that each of them has different LOD and each one has its advantages. The localized surface plasmon resonance (LSPR) biosensor which was developed in 2020 and used a U-shaped multi-mode fiber (U-MMF) [39] displayed high sensitivity, stability, and repeatability, whilst the Fiber-optic-based localized surface plasmon resonance (FO-LSPR) sensors with three-dimensional (3D) nanostructures which were developed in 2019 [68] displayed also high sensitivity of 404% with real-time label-free biosensors and the one which also was LSPR biosensor based on plasmonic capillary developed in 2018 provide an easier way of collecting liquid samples like urine, blood and body fluids by simply dipping or piercing and investigate directly without extra sampling work [70]. Diverse types of optical fiber-based LSPR sensors for the detection of bovine serum albumin (BSA) protein, the transmission-mode localized surface plasmon resonance biosensor chip which used multi-mode fiber in its design [73] exhibited LOD as low as 0.075 ng/ml which is better than the LSPR sensor which used a multimode -clad free fiber biosensor [10] which exhibited a higher LOD of 0.18 ng/ml and both of them are better than the Tapered Fiber Optic Biosensor (TFOBS) which based on Evanescent field absorption [77] which exhibited an LoD of 0.3263 gm/dL.…”

Preparation of Gold Nanoparticles Doped Zinc Oxide Using Reactive Pulsed Laser Ablation in Liquid

“…The deposition process was repeated for the etched fiber at 532 nm. With rising gold concentrations, this peak becomes more intense [27][28][29][30]. Figure 3b presents the XRD pattern, and it appears as a distinct peak.…”
