    Incorporation of the V3+ and V4+ ions into the yttrium aluminum garnet Y3Al5O12 (YAG) lattice has been studied by the correlated optical absorption and electron paramagnetic resonance (EPR) measurements. Only the V3+ ions at both octahedral and tetrahedral aluminum sites are found in as-grown crystals. However, annealing in air leads to the transformation of the V3+ to V4+, whereas annealing in the hydrogen atmosphere remains the V3+ concentration almost unchanged. The obtained EPR data on vanadium ions allow to improve identification of the optical absorption peaks in YAG:V crystals.
