The garnet-type structure has the cubic symmetry of space group Ia 3 ¯ d (No. 230) as shown in Fig. 1 [1]. The general chemical formula for a garnet oxide is written as {C} 3 [A] 2 (D) 3 O 12, with eight of these formula units per unit cell.The three cation sites are C-, A-, and D-sites, here { }, [ ], ( ) represent 24c (dodecahedral), 16a (octahedral) …
In this work, we report on the infrared (pump) to visible luminescence of Nd 3+ ion in Ca 3 Ga 2 Ge 3 O 12 for different Neodymium concentrations. Three visible structured emission bands centred at 541, 601 and 677 nm are observed, which are related to emissions mainly from the excited state 4 G 7/2.The relative intensity between the red …
Mixed rare earth iron garnet films containing calcium and germanium have been grown on (111) oriented gadolinium gallium garnet (GGG) substrates. The effect of growth conditions on film composition and properties is discussed. The 5 μm diameter bubble films have good magnetic properties; however, temperature control during film growth is very critical.

Measurements have been made of the electrode potential of p- and n-type germanium in contact with aqueous solutions of KOH, KCl and HCl as a function of anodic and cathodic current and of incident light intensity. For anodic currents, the measured electrode potential can be separated into three parts: the reversible electrode potential corresponding to the …
Lutetium aluminium garnet, Lu 3 Al 5 O 12 (LuAG) Lutetium aluminium garnet (Lu 3 Al 5 O 12, or LuAG) is a synthetic garnet crystal.Owing to its outstanding properties, such as high density, high thermal conductivity, and good transparency in the visible and near-infrared regions, it's widely used in scintillator applications for high-energy photon detection.
