  • Lecointre, A.; Bessiere, A.; Bos, A.J.J.; Dorenbos, P.; Viana, B.; Jacquart, S. (Journal of Physical Chemistry C. 115(10); 2011; 4217-4227.)
    Yttrium phosphates codoped (Ce3+,Ln(3+)) and (Pr3+,Ln(3+)) with Ln = Nd, Er, Ho, Dy were investigated by thermally stimulated luminescence. Similar to Ce3+, Pr3+ was found able to trap holes up to high temperatures While ...
  • Lecointre, A.; Bessiere, A.; Viana, B.; Gourier, D. (Radiation Measurements. 45(41704); 2010; 497-499.)
    Red persistent luminescent diopside nanoparticles doped with Mn(2+) and codoped with RE(3+) (Eu(2+), Dy(3+)) have been obtained by sol-gel method.The influence of codoping rare earth ions on the persistent luminescence was ...
  • Bessiere, A.; Lecointre, A.; Priolkar, K.R.; Gourier, D. (Journal of Materials Chemistry. 22(36); 2012; 19039-19046.)
    CaMgSi(2)O(6):Mn diopsides are used for in vivo long-lasting phosphorescence (LLP) imaging. Trapping defects involved in the LLP mechanism were investigated. On annealing Mn-doped diopsides at 1100 degrees C in an Ar-H-2 ...
  • Lecointre, A.; Bessiere, A.; Priolkar, K.R.; Gourier, D.; Wallez, G.; Viana, B. (Materials Research Bulletin. 48(5); 2013; 1898-1905.)
    Materials with red long-lasting phosphorescence, such as MnII-doped diopsides, can be used for small animal in vivo imaging. CaMgSi2O6:Mn powders with various amounts of Mn were prepared by sol-gel to investigate their ...
  • Lecointre, A.; Bessiere, A.; Viana, B.; AitBenhamou, R.; Gourier, D. (Radiation Measurements. 45(41704); 2010; 273-276.)
    The series of whitlockite compounds Ca(3)(PO(4))(2) and Ca(9)Ln(PO(4))(7) (Ln = Pr, Eu, Tb, Dy, Ho, Er, Lu) was studied in radioluminescence (RL) and thermally stimulated luminescence (TSL) excited by X-rays. f-f emission ...
  • Bessiere, A.; Jacquart, S.; Priolkar, K.R.; Lecointre, A.; Viana, B.; Gourier, D. (Optics Express. 19(11); 2011; 10131-10137.)
    ZnGa(2)O(4):Cr3+ is shown to be a new bright red UV excited long-lasting phosphor potentially suitable for in vivo imaging due to its 650 nm-750 nm emission range. Photoluminescence and X-ray excited radioluminescence show ...
