The Hamiltonian of neodymium and erbium ions in low‐symmetric crystal fields of KLn(MeO 4 ) 2 (Me = Mo, W and Ln = Y, Gd, Er, and Lu) crystals is constructed with fifteen crystal field parameters calculated within the framework of the exchange charge model. The theory using only one empirical scaling factor gives a satisfactorial description of Nd 3+ and Er 3+ ion spectra Stark structure and of its changing in the homologous series of tungstates investigated by absorption and luminescence.
