On the Origin of the Large Stokes-Shift of the Emission of CdS Nanoparticles Embedded in a Phosphate Glass Matrix

Carbon nanodots with a controlled N structure by a solvothermal method for generation of reactive oxygen species under visible light

“…The large Stokes shift of ~100 nm indicates that much of the absorbed energy decays via a nonradiative process. [ 40 ] We measured the 2D excitation–emission matrix (EEM) spectra of the B‐CNDs and G‐CNDs (Figure 2(a) and 2(b)); the emission and excitation maxima are observed at 432 nm (em) and 336 nm (ex) for B‐CNDs, and at 518 nm (em) and 389 nm (ex) for G‐CNDs.…”

Elaboration and characterization of new phosphate glasses based on natural phosphate and red clay: influence of the chemical composition on the chemical durability

“…Phosphate glasses (PGs) currently compete with silica glasses because are characterized by their high UV transparency, low IR transparency, and high thermal expansion, as well as their electrical and optical characteristics. Owing to these properties, phosphate glasses offer a unique range of applications, such as glass-polymer composite materials 1 , slow-release fertilization 2 , nuclear waste immobilization matrices 3 , conductive materials 4 amorphous semiconductors 5 , optical waveguides 6 , and solid-state laser 7 .…”
