摘要：
Mechanisms of the Cr reversible reaction Nd excitation energy transfer in Li-La//1// minus //x// minus //y-Nd//x-Cr//y phosphate glasses were investigated. It was established that the interaction between chromium and neodymium ions is of the dipole-dipole nature. It was found that at T equals 77 degree K the transfer of energy from chromium to neodymium ions is purely static and is accelerated by energy migration between chromium ions when the temperature is increased to room temperature. Energy transfer from neodymium to chromium ions is due to the static mechanism and also to hopping quenching under conditions of migration between neodymium ions. These and other results are presented and discussed.
