Novel Visible Emission and Mechanism Investigation from PbS Nanoclusters-Doped Borosilicate Glasses
Borosilicate glasses doped with PbO, ZnS, or PbS were fabricated to investigate the visible emissions (one located at 370 nm and another at 550 nm) observed in the PbO and ZnS codoped glass. Several series of glassy systems were designed to investigate the mechanism of above visible emissions. The a...

Summary: | Borosilicate glasses doped with PbO, ZnS, or PbS were fabricated to investigate the visible emissions (one located at 370 nm and another at 550 nm) observed in the PbO and ZnS codoped glass. Several series of glassy systems were designed to investigate the mechanism of above visible emissions. The absorption, photoluminescence (PL), photoluminescence excitation (PLE) spectra, and lifetime measurements were used to characterize all the emissions. The nanosecond level lifetimes for all the samples' 370 nm emissions ascribed the 370 nm emission to the glass defects. Measured lifetimes for the PbS quantum dots (QDs) in the glasses with an emission in the near‐infrared region which was about 8 μs was close to the values for the yellow emission, which confirmed the formation of PbS nanoclusters in the codoped glass was responsible for the yellow emission. |
