“…By avoiding complications due to charge extraction, it can provide insight more specifically regarding the local semiconductor quality. [110,111] As such, XEOL is valuable for understanding defects and carrier recombination mechanisms. [112] XEOL is distinguished from photoluminescence (PL) by the energy of the incident beam.…”

“…However, the proportional variation is an approximation. In isostructural semiconductors, such as CdS ( E g , 2.43 eV) and CdSe (1.74 eV), both being hexagonal, a “bowing parameter” is required to elucidate the E g of a material of intermediate composition [ 32,33 ] Enormalg(CdSySe1y)=yEnormalg(CdS)+(1y)Enormalg(CdSe)y(1y)β…”

“…CdS and CdSe form a complete solution, the main phase determined by XRD has a wurtzite structure with lattice parameters (a=b=4.19Å and c=6.82Å) matching a composition close to x=0.79. The colour ranges from yellow (pure CdS), to orange for x=0.81, red for x=0.65 and brown for x=0.25 [19]. The chemical composition of the cadmium sulphide selenide particles has been defined by SEM-EDS.…”

“…The composition is adequate to obtain a red ruby colour at a temperature close to the enamels firing temperature (≈590 o C). Higher firing temperatures favour the formation of crystals richer in Se, and lower firing temperatures produce crystals richer in S [19].…”
