Glass-ceramics containing rare earth gallium garnets were obtained using glass compositions as reactional medium. This work reports on the synthesis, and structural, morphological, optical characterizations of Er3+ Tm3+-doped Yb3Ga5O12 crystals prepared from controlled cooling heavy metal oxide melts. Micrometric cubic by controlling a earth-supersaturated glassy composition melted at high temp...

Single-crystal fibers are an intermediate between laser crystals and doped glass fibers. They have the advantages of both guiding laser light and matching the efficiencies found in bulk crystals, which is making them ideal candidates for high-power laser and fiber laser applications. This work focuses on the growth of a flexible fiber with a core of dopant (Er, Nd, Yb, etc.) and a polycrystalli...

Abstract The Flinton Group is a metasedimentary succession of the Grenville Province in SE Ontario, potentially allowing insight into tectono‐thermal evolution continental crust during Mesoproterozoic. At its Green Bay locality, metapelites staurolite zone contain abundant, post‐kinematic garnet porphyroblasts. Whereas larger crystals are typically impinged, smaller isolated from each other, oc...

EPR spectra of Ho 3+ impurity ions were recorded in single crystals yttrium aluminum garnet (Y 3 Al 5 O 12 ) the frequency range 114-170 GHz, at a temperature 4.2 K. The measurement results indicate substitution for Y dodecahedral position with D 2 local symmetry. magnitude g-factor, hyperfine structure constant, and energy interval between main first excited nondegenerate sublevels multiplet I...

Recent work in Barrovian metamorphic terranes has found that rocks experience peak metamorphic temperatures across several grades at similar times. This result is inconsistent with most geodynamic models of crustal over-thickening and conductive heating, wherein rocks which reach different metamorphic grades generally reach peak temperatures at different times. Instead, the presence of addition...

the formation of atoll garnet in hornblende schists from the contact aureole of mashhad granite,ne iran, is discussed using textural and chemical data. these data suggest the possibility of incipientreplacement of pre-existing idioblastic garnet from the core. in addition, the presence of chlorite and calcite inthe core of atoll garnet reveal the retrograde nature of atoll formation.

The portability of new miniaturized devices, together with their ability to connect conveniently to networks in different places, makes mobile computing possible. Recent advances that have led to increasing bandwidths, for wireless communications, enable mobile users to utilize a vast range of sophisticated services such as real-time collaborative services. Garnet Collaborative system is a univ...

An overview of different types mineralization in the area Urdini Lakes and glacial valley Urdina River (northwestern Rila Mountain) has been made. Currently, it is only protected for minerals Bulgaria. In this area, mainly pegmatite, but also skarn alpine-type mineralizations, have found to date. Of particular interest are hybrid desilicified type pegmatites containing emerald, aquamarine chrys...
