M. Wiegel et G. Blasse, NONLINEAR-OPTICAL PROPERTIES AND LUMINESCENCE OF KNBB2O6 AND RBNBGEO5, European journal of solid state and inorganic chemistry, 31(11), 1994, pp. 985-993
The nonlinear optical properties and luminescence of two new materials
, viz. KNbB2O6 and RbNbGeO5, are investigated and discussed in relatio
n with their crystal structure.
