Perspectives of a Four Center Cooperative Process in Rare Earth Doped Crystals
K. C. Mishra, John Collins
We have investigated the possibility of realizing a 4-center energy transfer among trivalent rare Earth ions in suitable hosts. A 4-center energy transfer process was originally proposed in the context of photo-physics of dendrimer molecular systems using molecular quantum electrodynamics methods. Later, a similar theoretical construct was proposed for rare Earth ions in crystalline solids. Here, we search for rare Earth ions suitable for 4-center energy transfer based on observed energy levels of 4f n multiplet structures in suitable hosts. A search for this 4-center cooperative energy transfer process experimentally will open a novel area of research in luminescence.
