Title: Evaluation of critical distances for energy transfer between Pr{sup 3+} and Ce{sup 3+} in yttrium aluminium garnet

Abstract

A series of Pr{sup 3+}/Ce{sup 3+} doped yttrium aluminium garnet (Y{sub 3}Al{sub 5}O{sub 12} or simply YAG) phosphors were synthesized to investigate the energy transfer between Pr{sup 3+} and Ce{sup 3+} for their potential application in a white light-emitting diode and quantum information storage and processing. The excitation and emission spectra of YAG:Pr{sup 3+}/Ce{sup 3+} were measured and analyzed, and it revealed that the reabsorption between Pr{sup 3+} and Ce{sup 3+} was so weak that it can be ignored, and the energy transfer from Pr{sup 3+} (5d) to Ce{sup 3+} (5d) and Ce{sup 3+} (5d) to Pr{sup 3+} ({sup 1}D{sub 2}) did occur. By analyzing the excitation and the emission spectra, the energy transfer from Pr{sup 3+} (5d) to Ce{sup 3+} (5d) and Ce{sup 3+} (5d) to Pr{sup 3+} ({sup 1}D{sub 2}) was examined in detail with an original strategy deduced from fluorescence dynamics and the Dexter energy transfer theory, and the critical distances of energy transfer were derived to be 7.9 Å and 4.0 Å for Pr{sup 3+} (5d) to Ce{sup 3+} (5d) and Ce{sup 3+} (5d) to Pr{sup 3+} ({sup 1}D{sub 2}), respectively. The energy transfer rates of the two processes of various concentrations were discussed and evaluated. Furthermore, formore » the purpose of sensing a single Pr{sup 3+} state with a Ce{sup 3+} ion, the optimal distance of Ce{sup 3+} from Pr{sup 3+} was evaluated as 5.60 Å, where the probability of success reaches its maximum value of 78.66%, and meanwhile the probabilities were evaluated for a series of Y{sup 3+} sites in a YAG lattice. These results will be of valuable reference for achievement of the optimal energy transfer efficiency in Pr{sup 3+}/Ce{sup 3+} doped YAG and other similar systems.« less

  • The results of the luminescence-quenching measurements of the {sup 4}{ital S}{sub 3/2} level of Er{sup 3+} in yttrium aluminum garnet are reported. Decay data in a large temperature (10--300 K) and concentration range (0.1--100 at.%) are analyzed. The quenching process depends strongly on concentration and temperature. At low Er{sup 3+} content ({le}3 at.%) the quenching is dominated by two-ion dipole-dipole cross-relaxation processes. It is shown that the previous proposed mechanisms can only explain the high-temperature data, and a possible active mechanism at low temperatures is proposed. At higher concentrations the quenching process depends strongly on temperature, the migration on donorsmore » playing an essential role, especially at low temperatures, where the supermigration regime is observed. The quadratic concentration dependence of the transfer parameters at high Er{sup 3+} content is connected with the three-ion cross-relaxation processes. The temperature dependences of the supermigration rates are consistent with two types of three-ion processes, i.e., one phonon-assisted process at low temperatures ({ital T}{lt}100 K) and another very efficient resonant one (({sup 4}{ital S}{sub 3/2},{sup 2}{ital H}{sub 11/2}){r arrow}{sup 4}{ital I}{sub 15/2}){sub {ital D}}+({sup 4}{ital I}{sub 15} 2{r arrow}{sup 4}{ital I}{sub 13/2}){sub {ital A}1}+({sup 4}{ital I}{sub 15/2}{r arrow}{sup 4}{ital I}{sub 9/2}){sub {ital A}} at high temperatures ({ital T}{gt}150 K). It is shown that at 300 K for {ital C}{gt}10 at.% Er{sup 3+} the transfer is of direct donor-acceptor type, due to the above cross relaxation. Thus, at 300 K, the energy from the pumping {sup 4}{ital S}{sub 3/2} level is transferred to the 3-{mu}m laser levels ({sup 4}{ital I}{sub 11/2} and {sup 4}{ital I}{sub 13/2}) by a three-ion cross relaxation.« less
  • The authors show that the luminescence radiation leaving through a lateral surface of the active element can reach a significant intensity and limit the energy efficiency of single-pulse laser systems with neodymium crystals because of the effect of a reflector after multiple passage through an active medium with a high gain coefficient. When the conditions leading to the development of this radiation within the reflector volume become less favorable, the emission energy and the gain coefficient of such systems increase.
  • We investigate the crystalline growth of yttrium iron garnet (YIG) films doped with bismuth (Bi) and cerium (Ce) by combinatorial pulsed laser deposition, co-ablating a YIG target and either a Bi{sub 2}O{sub 3} or a CeO{sub 2} target, for applications in microwave and optical communications. Substrate temperature is critical for crystalline growth of YIG with simultaneous inclusion of Bi in the garnet lattice, whereas Ce is not incorporated in the garnet structure, but forms a separate CeO{sub 2} phase.
  • Data indicating energy transfer between erbium and neodymium in yttrium aluminum garnet have been analyzed. The observed rate of transfer cannot be explained by the standard model, which assumes that the transfer occurs through the dipole-dipole interaction between randomly distributed acceptors and donors. A new model for energy transfer is presented in which donors and acceptors affect each other's placement in the crystal. A much closer fit to the observed experimental data is obtained with this model and by assuming that the location of erbium ions in the nearest-neighbor sites to neodymium ions is not energetically favorable.
