“…The luminescence of silver could be induced by irradiating the silver metal with electron, photon or laser beams with reported emission peak position. [47][48][49] The luminescence of the silver metal is attributed to the electronic transitions between the upper d-band and conduction sp-band. [50] The luminescence spectra of the AgNPs stabilized by hydrogel networks clearly demonstrate an emission peak at 466 nm upon excitation at 404 nm (Figure 3(b)).…”

Summary: This paper describes a simple and facile approach to fabricate well dispersed silver nanoparticles (AgNPs) in poly[N‐isopropylacrylamide‐co‐(sodium acrylate)] hydrogels. The silver nanoparticles formed are spherical in shape with a narrow size distribution in the hydrogel networks in which the nanoparticles are stabilized by the polymer network. Uniformly dispersed silver nanoparticles were obtained with poly[N‐isopropylacrylamide‐co‐[sodium acrylate)] hydrogels, whereas a poly(N‐isopropylacrylamide)/poly(sodium acrylate) IPN gel showed aggregated nanoparticles. It is demonstrated that the hydrogel network structure determines the size and shape of the nanoparticles. These particles are more stable in the gel networks compared to other reduction methods. The hydrogel/silver nanohybrids were well characterized by XRD, UV‐vis spectrometry, scanning electron microscopy and transmission electron microscopy.

“…This discussion is pertinent to a large class of experiments on fluorescence and Raman scattering from molecules on metal-island films [51][52][53], on particle arrays [54,55], and in metal-colloid solutions [56][57][58][59]. Theoretical treatments of this problem have been given by several authors [60][61][62].…”
