Název v původním jazyce

Stokes 1.5 ?m anti-Stokes 0.99 ?m emissions in Ga-Ge-Sb-S: Er3+ amorphous chalcogenide films prepared by pulsed laser deposition

Popis výsledku v původním jazyce

Nowadays, rare-earth-doped materials play an important role in photonics. The reason can be seen in needs of present world for efficient data transfer, medical use, construction of modern devices and in research progress. We report the compositional dependence of Ga-Ge-Sb-S: Er3+ pulsed laser deposited (PLD) chalcogenide films allowing the efficient Er3+: 4I13/2 RIGHTWARDS ARROW 4I15/2 (? ALMOST EQUAL TO 1.5 ?m) Stokes and Er3+: 4I11/2 RIGHTWARDS ARROW 4I15/2 (? ALMOST EQUAL TO 0.99 ?m) anti-Stokes emissions at pumping wavelength of 980 and 1550 nm, respectively. It was found that the lowers antimony and the highest sulphur contents in Ga-Ge-Sb-S films doped with 0.5 at.% Er3+ are beneficial for both mentioned emissions. The photon up-conversion emission was confidently observed in the case of PLD film with the highest content of sulphur, i.e., (Ge17.8Ga3.6Sb3.6S75)99.5Er0.5. The shape of this emission band is comparable with the photon up-convesion emission observed in the bulk sample
