Abstract

Efficient energy transfer at room temperature from Tm 3 + to Pr 3 + has been demonstrated in co-doped K Pb 2 Cl 5 . Because of the low phonon energies in K Pb 2 Cl 5 , the energy transfer processes result in the conversion of 805 nm laser diode pump energy to a broad band of mid-IR radiation between 3500 to 5500 nm . Energy transfer pathways, rates, and quantum efficiencies are evaluated. Results show that the material is suitable as a phosphor for the 4 to 5 μ m spectral range that can be optically pumped with low-cost 0.8 μ m laser diodes.
