Growth and optical spectroscopy of KPb2Cl5 crystal containing Mn2+

Modulating luminescence properties of CsMnBr3-based lead-free single crystals by pseudohalide doping

“…3c. 35 The emission of six-coordinated Mn 2+ ions was attributed to the transition from 4 T 1 ( 4 G) to 6 A 1 ( 6 S), which is represented by the dashed line in the diagram.…”

Optical and photoelectron spectroscopy studies of KPb2Cl5 and RbPb2Cl5 laser crystals

“…The laser generation of KPb 2 X 5 : RE crystals has been obtained with Nd 3+ (1.06 lm), Dy 3+ (2.4 lm) [3,7], and Er 3+ ions (4.6 lm) [10,11]. In this regard, many research works were devoted to luminescence spectroscopy of APb 2 X 5 crystals doped with various impurity ions, among them U 3+ [12], Yb 3+ [13], Pr 3+ [14], Er 3+ [15][16][17], Ho 3+ [18] and Mn 2+ [19]. At the same time, very few papers were devoted to study of the APb 2 X 5 host crystal.…”
