Crystal growth of Cr, Ca(Mg):Y3Al5O12 with high Cr4+-doping concentration

Not Accessible

Your library or personal account may give you access


When chromium is doped into Y3Al5O12 (YAG), it substitues for aluminimun and normally occupies octahedral sites as Cr3+, However, the active center giving 1.35-1.6-μm emission is Cr4+, Therefore, obtaining high concentrations of Cr4+ and to therefore improve the NIR absorption, is the key to grow Cr4+-doped YAG crystals.
