| Popis: |
Spectroscopic characteristics of the lower lying energy levels of Pr3+ doped into the low-phonon energy hosts CsPbCl3 and TlPb2Br5 were explored for mid-IR laser applications. Both crystals posses relatively large IR absorption cross-sections for their 3F4+3F3 and 3F2+3H6 excited states, which indicates efficient optical pumping at either ~1.5 µm and ~2.0 µm, respectively. Pr: TlPb2Br5 exhibited an efficient MIR emission at room temperature with a lifetime of ~37 ms making it a promising candidate for laser applications. Only weak MIR emission was observed from Pr: CsPbCl3 due to strong emission quenching. More details of the IR spectroscopy including temperature dependent spectral and lifetime studies will be presented at the conference. |
