We identified the origin of the blue and green upconverted fluorescence observed as being due to a Ho 3+-Ho 3+ pair interaction process. The dynamics of the fluorescence revealed the pathways involved in the energy transfer assisted upconversion process. © 2002 American Institute of Physics.1272-1276engFluoroindate glassFrequency up-conversionPair interactionsUp-conversion processFluorescenceGlassEnergy transferArtigo10.1063/1.1430889Acesso aberto2-s2.0-00364693632-s2.0-0036469363.pdf2998503841917815
