Stoichiometry deviations in aluminium and gallium garnet crystals are investigated by measuring the spectra of rare‐earth impurities ions as indicator. All garnet crystals prepared from the melt are found to have a nonstoichometric composition due to incorporation of some part of the rare‐earth ions into Al3± or Ga3± octahedral sites. The stoichiometry deviations in the homologous series of aluminium and gallium garnet crystals are estimated quantitatively. The spectra of Er3± ions occupying a‐sites with octahedral oxygen environment in garnet lattice are registered and studied. An effect is found of difference in the sizes of the rare‐earth ions on their co‐occupation of octahedral sites in the gallium garnet lattice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
