Description
Luminescence, time-resolved luminescence and decay profiles are measured in order to investigate quantum-confinement effects in alumina(Al2O3)-modified MCM-41 silica nanotubes doped with ZnxCd1-xS:Eu3+, Tb3+ nanocrystals at temperatures down to 10 K. In comparison with bulk materials, in the presence of vibronic luminescence bands, luminescence spectral characteristics are found associated with SiO2 centers, a new f-f transition mechanism and very short (600 ps) lifetime features due to surface-bound centers
