Abstract
The conditions for growth of single crystals of potassium dihydrogen phosphate KH2PO4 activated by organic phosphors were investigated. Aqueous solutions of derivatives of naphthalic and perylenetetracar-boxylic acids were used as activators. A possible scheme of coherent matching of crystallochemical parameters of the KH2PO4 lattice with an organic activator molecule is proposed. The excitation and photoluminescence spectra of the activated crystals are measured in the range 200–600 nm. It is ascertained that the luminescence is related to the presence of organic phosphors in the KH2PO4 lattice.
