Engineering of Solar Energy Harvesting Tb³⁺-Ion-Doped CdS Quantum Dot Glasses for Photodissociation of Hydrogen Sulfide.

ABSTRACT: The photocatalytic properties of CdS quantum dots (Q-dots) and Tb³⁺-doped CdS Q-dots dispersed in a borosilicate glass matrix were investigated for the photodissociation of hydrogen sulfide (H₂S) into hydrogen (H₂) gas and elemental sulfur (S). The Q-dot-containing glass samples were fabricated using the conventional melt-quench method and isothermal annealing between 550 and 600 °C for 6 h for controlling the growth of CdS and Tb³⁺-ion-doped CdS Q-dots. The structure, electronic band gap, and spectroscopic properties of the Q-dots formed in the glass matrix after annealing were analyzed using Raman and UV-visible spectroscopies, X-ray powder diffraction, and transmission electron microscopy. With increasing annealing temperature, the average siz
