Peculiarities of the manifestation for cascade emission in polyphosphate systems involving ions Pr3+ and Gd3+, and energy transfer in pairs of ions Gd3+ – Eu3+, Pr3+ – Ce3+ and Gd3+ - Ce3+ are revealed. The micro-and nanocrystals LaX3, activated by cerium ions, embedded in a matrix NaX are shown to be formed in the systems NaX-LaX3-CeX3 (X = Br, I). The basic mechanisms of luminescence excitation in cerium centers of micro- and nanocrystals LaX3 (X = Br, I) are specified.
