Distribution coefficients of Nd3+, Tm3+ and Er3+ in calcium niobium gallium garnet (CNGG) single crystals have been investigated. The values of the equilibrium distribution coefficient, ко, of Nd3+, Tm3+ and Er3+ in CNGG single crystals have been determined to be 0.55, 1.09 and 1.14, respectively. It is shown that the distribution coefficients of Nd3+ in CNGG single crystals are larger than those in other garnet crystals such as Y3AI5O12 and GdsGa5 0i2. The variation of the ко values is discussed in relation to the ionic radii of each of the cations.
