“…The growth conditions of pure or RE 3+ -doped APb 2 X 5 (A=K,Rb ; X=Cl,Br) and Tl 3 PbX 5 (X=Cl,Br) single crystals for MIR laser and/or nonlinear optical applications have been exhaustively detailed in an impressive body of work [Amedzake et al, 2008;Atuchin et al, 2011;Bekenev et al, 2011;Condon et al, 2006b;Ferrier et al, 2006aFerrier et al, , 2006bGang et al, 2008;Isaenko et al, 2001;Nitsch et al, 1993Nitsch et al, , 1995aNitsch et al, , 1995bNitsch et al, , 2004Nitsch & Rodová 1999;Oyebola et al, 2010;Rodová et al, 1995;Roy et al, 2003;Singh et al, 2005;Tigréat et al, 2001;Velázquez et al, 2006aVelázquez et al, , 2006bVelázquez et al, , 2009Voda et al, 2004;Wang et al, 2007]. Special safety conditions for the manipulation of large amounts of TlCl or TlBr powders must be followed, but this does not entail insuperable difficulties [Peter & Viraraghavan, 2005].…”

“…Among them, the newly developed alkali metal lead double halide APb 2 X 5 (A = K, Rb; X = Cl, Br) crystal family is the promising host for embedding various rare-earth (RE) ions [1][2][3]. The APb 2 X 5 lattice provides a large isomorphous capacity for rare-earth and transition impurity ions and efficient channel of energy transfer from the host lattice to the impurity ions.…”

a b s t r a c tThe paper presents the results of experimental study of electronic structure of RbPb 2 Cl 5 and KPb 2 Cl 5 laser crystals performed by the optical and photoelectron spectroscopy methods. On the basis of the optical absorption and low-temperature reflection spectra of these crystals we have determined the energy positions of the edges of the low-energy tail of the host absorption, the positions of the first excitonic absorption peaks, and exciton binding energies. The bandgap widths of these crystals at 8 K were estimated as E g = 4.83 and 4.79 eV, respectively. Qualitative and quantitative analysis of RbPb 2 Cl 5 and KPb 2-Cl 5 crystals were made on the basis of the core states photoelectron spectra. The elemental composition of the (0 0 1) surfaces of the crystals, the chemical state of the host atoms, the electronic structure of the valence band of the crystals were discussed on the basis on the spectroscopic data.

“…The higher wavelength cutoff for KPb 2 Cl 5 is reported to be ϳ20 m. 5,8 The transmission of the undoped KPb 2 Br 5 was found to be about 80% from 1.5 m to 25 m. The refractive index was measured to be n = 2.1 at 1.5 m. 16 The refractive index was thus found to be very close to KPb 2 Cl 5 ͑n = 2.016± 0.005͒. Similar to KPb 2 Cl 5 , KPb 2 Br 5 also is colorless, hard, rugged, and very stable in normal atmosphere.…”

“…High power, portable, compact and easily deployed mid-IR solid-state lasers have several applications such as IR LIDAR remote sensing, free space communication, IR countermeasures, infrared imaging, and medical surgery. KPb 2 Cl 5 has recently emerged as a potential laser material operating at room temperature [1][2][3][4][5] with a low maximum phonon energy of 203 cm −1 , while the conventional oxides and fluoride hosts usually show a maximum phonon energy in the range of ϳ500 cm −1 and above. 6 Doping of rare-earth ions, such as Dy 3+ ,Nd 3+ ,Pr 3+ ,Yb 3+ ,Er 3+ , etc.…”

Crystals of potassium lead bromide (KPB), a moisture-insensitive low-energy phonon laser host, were synthesized and purified. High-quality undoped and Tb3+-doped (nominal doping concentration was 5mol% TbBr3) KPb2Br5 were grown by the vertical Bridgman technique. X-ray diffraction measurements indicated that, at room temperature, the material was monoclinic with space group P21∕c, while at a high temperature the phase transformed to orthorhombic form. A reversible phase transition was observed around 256°C upon the heating and cooling cycle from differential scanning calorimetric measurements. The material was found to be transparent in the broad range from ∼0.4μmto25μm and above. The transmission spectrum of a Tb3+-doped crystal showed different absorption bands of Tb3+ at 4.5μm, 3μm, 2.3μm, and 2μm corresponding to F67–Fα7 transitions, for α=2–5. The maximum phonon energy of undoped KPb2Br5 at room temperature was determined to be 134cm−1 from Raman scattering spectrum.
