[Improvement of anti-stokes energy transfer between rare earth ions--2. Numerical calculation and analysis].

The dynamics of all levels were calculated numerically in the present article for Er(0.5)Yb(3):FOV oxyfluoride nanophase vitroceramics. The population dynamical processes were analyzed carefully.

[Improvement in the calculation of anti-Stokes energy transfer between rare earth ions. 1. Experiment and theoretical basis].

A photonic phenomenon of fluorescence intensity reverse between red and green fluorescence was studied theoretically and experimentally in the present article. It was found by experiment that Er(0.5) Yb(9.

Three-photon infrared quantum cutting from single species of rare-earth Er3+ ions in Er0.3Gd0.7VO4 crystalline.

An effective three-photon IR quantum cutting excited by visible light used for solar cells, which has attracted broad attention of academia recently, is reported for the first time (to our knowledge). It is based on a single species of rare-earth Er3+ ion of Er0.3Gd0.

[The upconversion luminescence of Tm(0.35)Yb(5):FOV nanophase oxyfluoride vitroceramics].

The upconversion luminescence of nanophase oxyfluoride vitroceramics Tm(0.35)Yb(5) : FOV when excited by a 975 nm diode laser was studied in the present paper. Several ultraviolet upconversion luminescence lines positioned at 363.
