Abstract
The phenomenon of concentration quenching of the luminescence from donor io ns in crystals of La1 - xCexF3 solid solutions was studied. A cooperative n onradiative energy transfer from a single excited neodymium ion to a cooper ative acceptor representing a couple of cerium ions, as well as from a sing le erbium ion to three cerium atoms (also forming a cooperative acceptor ce nter), was observed.
