  • Does conserved domain SOD1 mutation has any role in ALS severity and therapeutic outcome? 
    Pal, S.; Tiwari, A.; Sharma, K.; Sharma, S.K. (BMC Neuroscience. 21; 2020; ArticleID_42.)
    Background: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative fatal disease that can affect the neurons of brain and spinal cord. ALS genetics has identified various genes to be associated with disease ...
  • The importance of inversion disorder in the visible light induced persistent luminescence in Cr sup(3+) doped AB(2)O(4) (A = Zn or Mg and B = Ga or Al) 
    Basavaraju, N.; Priolkar, K.R.; Gourier, D.; Sharma, S.K.; Bessiere, A.; Viana, B. (Physical Chemistry Chemical Physics. 2015(17); 2015; 1790-1799.)
    Cr sup(3+) doped spinel compounds AB(2)O(4) with A = Zn, Mg and B = Ga, Al exhibit a long, near infrared persistent luminescence when excited with UV or X-rays. In addition, the persistent luminescence of ZnGa(2)O(4), and ...
  • Interplay between chromium content and lattice disorder on persistent luminescence of ZnGa(2)O(4):Cr3+ for in vivo imaging 
    Sharma, S.K.; Bessiere, A.; Basavaraju, N.; Priolkar, K.R.; Binet, L.; Viana, B.; Gourier, D. (Journal of Luminescence. 155; 2014; 251-256.)
    In the quest of bright and long persistent far-red/near-infrared phosphors for in vivo optical imaging, the interest in the family of ZnGa(2)O(4) spinel compounds doped with Cr3+ has been aroused in the most recent years. ...
  • Optical properties and storage capabilities in AB2O4:Cr(A = Zn, Mg, B = Ga, Al) 
    Sharma, S.K.; Bessiere, A.; Gourier, D.; Sraiki, G.; Viana, B.; Dereo, P.J.; Rudnicka, D.; Watras, A.; Basavaraju, N.; Priolkar, K.R.; Maldiney, T.; Scherman, D.; Richard, C. (Proc. SPIE 8987. Oxide based Materials and Devices 5. 2014; 89870J-.)
    Red emitting long-lasting phosphorescence (LLP) material, are useful biomarker for small animal in vivo imaging. We report here our investigations on the optical features of chromium doped AB2O4 spinels (A=Zn, Mg and B=Ga, ...
  • Origin of the visible light induced persistent luminescence of Cr3+ -doped zinc gallate 
    Gourier, D.; Bessiere, A.; Sharma, S.K.; Binet, L.; Viana, B.; Basavaraju, N.; Priolkar, K.R. (Journal of Physics and Chemistry of Solids. 75(7); 2014; 826-837.)
    ZnGa2O4:Cr3+ (ZGO:Cr) is a very bright persistent phosphor able to emit a near infrared light for hours following a UV (band to band excitation) or visible (Cr3 excitation) illumination. As such it serves as an outstanding ...
  • Persistent luminescence in ZnGa2O4:Cr: An outstanding biomarker for in-vivo imaging 
    Sharma, S.K.; Bessiere, A.; Gourier, D.; Binet, L.; Viana, B.; Basavaraju, N.; Priolkar, K.R.; Maldiney, T.; Scherman, D.; Richard, C. (Proc. SPIE 8982, Optical Components and Materials. 2014; 898215-.)
    ZnGa2O4 (ZGO) is a normal spinel. When doped with Cr3+ ions, ZGO:Cr becomes a high brightness persistent luminescence material with an emission spectrum perfectly matching the transparency window of living tissues. It ...
