Decay kinetics of Mn²⁺ ion luminescence in Mg, Zn, and Cd silicates and fluorides
Kinetic properties of Mп²⁺ ions in Mg, Zп, Cd silicates and fluorides with red color luminescence have been studied. The luminescence decay time is increased when LaF₃ or LiF, CdF₂, YF₃ are introduced in the ZпF₂ or MgF₂ samples. The decay time and the kinetic curve shapes of the silicate phosphors...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Kinetic properties of Mп²⁺ ions in Mg, Zп, Cd silicates and fluorides with red color luminescence have been studied. The luminescence decay time is increased when LaF₃ or LiF, CdF₂, YF₃ are introduced in the ZпF₂ or MgF₂ samples. The decay time and the kinetic curve shapes of the silicate phosphors are modified due to co-activation (MgF₂, CaF₂, BaF₂ and SrF₂). This is associated with the energy transfer through the conduction zone from the electron traps to the activator ion.
Исследованы кинетические свойства ионов Mп²⁺ в силикатах и фторидах Mg, Zп и Cd с люминесценцией красного цвета. Время затухания люминесценции увеличивается при введении LaF₃ или LiF, CdF₂, YF₃в образцы ZпF₂ или MgF₂. Формы кривых затухания силикатных кристаллофосфоров изменяются при соактивации (MgF₂, CaF₂, BaF₂ and SrF₂). Это связано с переносом энергии через зону проводимости от электронных ловушек к ионам активатора.
