“…Materials with magnetoplumbite structure, doped with transition and rare-earth ions, are currently of interest both as laser and a phosphor hosts [6][7][8][9][10]. It has been reported in literature that Nd-activated LMA is a promising laser material, which could replace YAG:Nd for some of its applications [11][12][13]. In 1988, Viana et al [14] reported optical properties and crystallographic location of Ce 3+ in La 1À x Ce x MgAl 11 O 19 .…”
