4f2 to 4f5d excited state absorption in Pr3+-doped crystals

Nicolas S.; Descroix E.; Guyot Y.; Joubert M.; Abdulsabirov R.; Korableva S.; Naumov A.; Semashko V. (2001)

We first report one photon classical spectroscopy of Pr3+-doped LiLuF4 single crystals which leads to the energy level diagram for Pr3+ levels in this host and to the 1D2 and 3P0 emitting level lifetimes. Then, excited ...
Application of photoconductivity measurements to photodynamic processes investigation in LiYF 4:Ce 3+ and LiLuF 4:Ce 3+ crystals

Nurtdinova L.; Semashko V.; Guyot Y.; Korableva S.; Joubert M.; Nizamutdinov A. (2011)

Photoconductivity measurements are applied to the studies of photodynamic processes in LiYF 4:Ce 3+ and LiLuF 4:Ce 3+ crystals undergoing ultraviolet irradiation. Photoconductivity spectra were registered by means of ...
Potentiality of Pr3+- and Pr3+ + Ce3+ -doped crystals for tunable UV upconversion lasers

Nicolas S.; Descroix E.; Joubert M.; Guyot Y.; Laroche M.; Moncorgé R.; Abdulsabirov R.; Naumov A.; Semashko V.; Tkachuk A.; Malinowski M. (2003)

Gain experiments based on the interconfigurational 4f5d to 4f2 optical transitions in praseodymium-doped fluoride crystals were achieved. The measurements were performed under upconversion pumping of the 4f5d excited ...
Stark level structure and oscillator strengths of Nd3+ ion in different fluoride single crystals

Martín I.; Guyot Y.; Joubert M.; Abdulsabirov R.; Korableva S.; Semashko V. (2001)

Optical properties of three fluoride single crystals (YF3, LiLuF4 and KY3F10) doped with Nd3+ ions have been studied. Low temperature absorption spectra lead to the Stark energy level scheme up to 29 000 cm-1. From room ...
Unexpected luminescence of Cr5+ and Cr3+ ions in ZrSiO4 zircon crystals

Gaft M.; Boulon G.; Panczer G.; Guyot Y.; Reisfeld R.; Votyakov S.; Bulka G. (2000)

Luminescence, decay-times and EPR spectroscopy of Cr-doped ZrSiO4 show the presence of both Cr3+ and Cr5+ active centers, which can be connected with Zr4+ and Si4+ adjacent two-cation replacement. Cr5+ emission occurs ...
