Optical properties of phosphate glass with CdSe quantum dots in terahertz frequency range

Optical properties and spectral characteristics of phosphate glasses with CdSe QDs were studied using time-domain terahertz spectroscopy in transmission mode in the frequency range of 0.2 - 1.0 THz. Concentration and size of QDs were varied by changing heat treatment conditions of initial glass samp...

Beschreibung
Zusammenfassung:Optical properties and spectral characteristics of phosphate glasses with CdSe QDs were studied using time-domain terahertz spectroscopy in transmission mode in the frequency range of 0.2 - 1.0 THz. Concentration and size of QDs were varied by changing heat treatment conditions of initial glass samples containing components of the semiconductor phase. The change of refractive index and absorption coefficient at the high frequency edge of the investigated range at variation of secondary processing parameters was observed.
