“…[51] Figure 3c-e shows the PL emission of Si QDs embedded in SiO x , SiN x, and SiO x C y matrices. [22,27,52] Figure 3c shows the effect of annealing treatments on the QDs size distribution and hence, the control over different emissions at the visible region. It can be seen that different heat treatments induced a size change that further invoked the confinement effect, and overall an indirect-bandgap material was able to emit in different regions.…”

After the first visible photoluminescence (PL) from porous silicon (pSi), continuous efforts are made to fabricate Si‐based compound nanomaterials embedded in matrices such as oxide, nitride, and carbide to improve optical performance and industrial acceptability. These nanomaterials’ functional and desired properties (nanoparticles and quantum dots embedded in matrices) can vary significantly when embedded in technologically relevant matrices. However, exploring the exact emission mechanisms is one of the remaining challenges from the past few decades. To cover this gap, this review discusses the morphological and optoelectronic properties of Si‐based compound nanomaterials and their correlation with the quantum confinement effect and different surface states to find precise emission mechanisms. One of the biggest challenges of using silicon nanomaterials in the biological sector is the development of sensitive materials of low/acceptable toxicity for identifying target analytes either inside/outside the biological platforms. In this scenario, silicon‐based compound matrices can offer different characteristics and advantages depending on their size configurations and PL emission mechanisms. On the other hand, a proper understanding of these multifaceted silicon nanomaterials’ optical properties (emission mechanisms) can be exploited for pathogen detection and in situ applications in cells and tissues, embarking on a new era of bioimaging technology.

“…Hybrid composites with improved mechanical, electrical, and optical characteristics are well-designed materials with surface roughness. They can interfere with the incident light, creating a refractive index gradient, allowing the progressive bending of light rays, which, in turn, results in improved AR characteristics [2,3,4].…”

Antireflection Enhancement by Composite Nanoporous Zeolite 3A–Carbon Thin Film

et al. 2019

A straightforward and effective spin-coating technique at 120 °C was investigated for the deposition of a thin nanoporous layer with antireflection properties onto glass and indium tin oxide (ITO) coated glass. A mixture of zeolite 3A powder and high iodine value vegetable oil was deposited, creating a carbonic paste with embedded nanoporous grains. Experimental results evidenced excellent broadband antireflection over the visible-near-infrared wavelength range (450–850 nm), with a diffuse reflectance value of 1.67% and 1.79%. Structural and optical characteristics stabilized over time. The results are promising for the accessible and cost-effective fabrication of an antireflective surface for optoelectronic devices.
