Abstract :
Laser action of the TR:KPC (KPb2Cl5) crystals was achieved with Dy at 2.4 μm. In the present work we continued studying this new systems based on TR3+ doped chloride matrix suitable for diode-pumped lasers. We studied the optical spectra and luminescence kinetics, calculated radiative and nonradiative transition probabilities, considered up-conversion processes and possibility of energy transfer from exciton matrix band to TR3+ ions. Intensive absorption band in UV spectral range (λ<340 nm) associated with excitonic absorption formed by 6s→6p transitions in Pb2+ ion. TR3+ doped KPC crystals exhibit strong absorption bands in UV and IR.
