“…Owing to its unique optical properties, light-trapping structure plays a more and more important role in photovoltaic devices [1]. At present, researchers have developed all kinds of nanostructures as light-trapping structures to increase light absorption in photovoltaics, while most of them were performed on Si substrate [2][3][4][5][6]. III-V compound semiconductor nanostructures have been shown to be promising materials for a variety of optoelectronic and energy-related applications such as light-emitting diodes (LEDs) [7,8], photovoltaics (PV) [9][10][11][12] and field effect transistors (FETs) [13][14][15][16].…”

GaAs nanostructures have attracted more and more attention due to its excellent properties such as increasing photon absorption. The fabrication process on GaAs substrate was rarely reported, and most of the preparation processes are complex. Here, we report a black GaAs fabrication process using a simple inductively coupled plasma etching process, with no extra lithography process. The fabricated sample has a low reflectance value, close to zero. Besides, the black GaAs also displayed hydrophobic property, with a water contact angle of 125°. This kind of black GaAs etching process could be added to the fabrication workflow of photodetectors and solar cell devices to further improve their characteristics.

“…The field of research concerned with the study of this light-metal interaction is called 'plasmonics', which is part of a larger field of nanophotonics [1]. Plasmonics has found numerous applications in the fields such as Surface Enhanced Raman Scattering (SERS) [2][3][4][5], Tip Enhanced Raman Scattering (TERS) [6][7][8], Negative Index of Refraction (NIR) [9,10], solar cells [3,11], Localized Surface Plasmon Resonance (LSPR), etc. Techniques such as LSPR, TERS, and SERS have been extensively used for label-free sensing.…”

The influence of heat generation on the conventional process of LSPR based sensing has not been explored thus far. Therefore, a need exists to draw attention toward the heat generation issue during LSPR sensing as it may affect the refractive index of the analyte, leading to incorrect sensory conclusions. This manuscript addresses the connection between the photo-thermal effect and LSPR. We numerically analyzed the heat performance of a gold cladded nanotip. The numerical results predict a change in the micro-scale temperature in the microenvironment near the nanotip. These numerical results predict a temperature increase of more than 20 K near the apex of the nanotip, which depends on numerous factors including the input optical power and the diameter of the fiber. We analytically show that this change in the temperature influences a change in the refractive index of the microenvironment in the vicinity of the nanotip. In accordance with our numerical and analytical findings, we experimentally show an LSPR shift induced by a change in the input power of the source. We believe that our work will bring the importance of temperature dependence in nanotip based LSPR sensing to the fore.

“…In the last decades, there has been significant advances in both theoretical and experimental investigations of surface plasmons, which led to the development of new simulation methods to calculate the optical properties of nanoplasmonic systems [5,10,11], and has delivered a relevant number of important applications [12][13][14]. Among them, is the detection of biomolecules, either by plasmonic sensing [15][16][17][18][19][20][21], plasmon-enhanced fluorescence [22] or surface-enhanced Raman scattering (SERS) [23][24][25], the enhancement of absorbed light in solar cells [26][27][28][29], biological imaging and phototherapy of tumors [30][31][32], as well as photocatalytic applications [33][34][35][36][37].…”

Preparation of Plasmonic Au-TiO2 Thin Films on a Transparent Polymer Substrate

et al. 2020

In this work, plasmonic thin films composed of Au nanoparticles embedded in a TiO2 matrix were prepared in a transparent polymer substrate of poly(dimethylsiloxane) (PDMS). The thin films were deposited by reactive DC magnetron sputtering, and then subjected to heat treatment up to 150 °C in order to promote the growth of the Au nanoparticles throughout the TiO2 matrix. The transmittance spectrum of the thin films was monitored in situ during the heat treatment, and the minimum time required to have a defined localized surface plasmon resonance (LSPR) band was about 10 min. The average size of Au nanoparticles was estimated to be about 21 nm—the majority of them are sized in the range 10–40 nm, but also extend to larger sizes, with irregular shapes. The refractive index sensitivity of the films was estimated by using two test fluids (H2O and DMSO), and the average value reached in the assays was 37.3 ± 1.5 nm/RIU, resulting from an average shift of 5.4 ± 0.2 nm. The results show that it is possible to produce sensitive plasmonic Au-TiO2 thin films in transparent polymer substrates such as PDMS, the base material to develop microfluidic channels to be incorporated in LSPR sensing systems.
