Cooperative luminescence quenching on many-particle acceptors in disordered media

Basiev, T.T.; Basieva, I.T. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 12, pp. 3526-3532

Many-body cooperative energy transfer is an important process in biology, medicine, photosynthesis, rare-earth-doped laser materials, responsible for up- and down-conversion of energy, optical excitation sensitization and relaxation. We present an analytical solution for long-time asymptotic of...

An electron paramagnetic resonance (EPR) study of Er<Superscript>3+ </Superscript> ions in single crystals of RbTiOPO<Subscript>4</Subscript> (RTP) is presented. The EPR spectra show the existence of six different Er<Superscript>3+</Superscript> centres. The g-matrix has been determined for these centres from the analysis of the angular dependences of the spectrum in...</superscript></subscript></superscript>
