Aqueous Sol-Gel Synthesis Methods for the Preparation of Garnet Crystal Structure Compounds

Abstract

In the present review, the usefulness of aqueous sol-gel processes in the synthesis of garnet crystal structure compounds is discussed. The processing and characterization of yttrium aluminium garnet (YAG), lanthanide-doped YAG, lanthanide aluminium and gallium garnet materials, mixed-metal garnets and garnets containing silicon are described. The synthesis of garnet materials comprising nanoscale architectures is also discussed.<p><a href="http://dx.doi.org/10.5755/j01.ms.17.4.782">http://dx.doi.org/10.5755/j01.ms.17.4.782</a></p

Sol–gel synthesis, characterization and study of substitution effects in different gallium-containing garnets

“…The improvements in physical properties and the new areas of applications provide a strong motivation for studying garnets in general [51]. The most promising materials for photomorphogenetic LEDs are those based on GSGG, GGG, YGG and LuGG, since they exhibit the most suitable PL spectra and are characterized by the relatively high values of QE.…”

Recent Developments in Lanthanide-Doped Alkaline Earth Aluminate Phosphors with Enhanced and Long-Persistent Luminescence

“…Both nonaqueous and aqueous sol–gel methods have been employed. The aqueous sol–gel process is considered better than the nonaqueous process because the former facilitates the formation of a homogeneous solid-state structure at the atomic level, which is based on the chemical interactions among the precursor species in the mixture [ 65 ]. Misevicius et al employed this concept in using the aqueous sol–gel approach for the synthesis of various Ce-doped strontium aluminates using glycolate intermediates, such as SrAl 2 O 4 , Sr 3 Al 2 O 6 , and Sr 4 Al 4 O 10 [ 52 ].…”

Sol–gel derived Tb3Fe5O12 and Y3Fe5O12 garnets: Synthesis, phase purity, micro-structure and improved design of morphology

“…A lot of different synthesis methods have been used to synthesize YIG including solegel [15e18], self-combustion [17], microwave [19], and solidstate [20] methods. Solegel process has considerable advantages compared to other synthesis methods because of better homogeneity, lower temperatures, and controlled properties of final product [21,22]. Moreover, in recent years, great interest has been focused on nanoparticle studies and in particular on the relationships between size and physical properties [8].…”
