Crystal growth, optical absorption, emission spectra and fluorescence decay times of calcium-and vanadium-doped Gd,Ga,O,, garnet are reported. The observed optical spectra are assigned to V4+ ions in octahedral and tetrahedral sites. A broad red luminescence in the 600-800 nm region is shown to be d
The crystal growth rate of CaS03 \* V2H20 was measured by a pH-stat method in aqueous solution with pH 3.5 to 6.5, 1 to 25 mM dissolved sulfite, 0.01 to 0.3 M Ca", and 0 to 25 mM sulfate. The growth rate was a strong function of relative supersaturation and was strongly inhibited by dissolved sulfat
