“…Recently, the interesting research on electron beam induced second harmonic generation has been reported in Er 3+ doped PbO-GeO 2 glass containing silver nanoparticles [22]. Such a remarkable phenomenon allows the possibility of 3-D multi-coloured images or bright light-emitting devices (LEDs) with tunable emission colours [23] in this activated glass.…”

We have systematically investigated the X-ray-induced radiophotoluminescence (RPL) bands in a silver-activated phosphate glass (PG:Ag), and we have ascribed these bands to Ag 0 , Ag 2+and Ag 2 + centres, using optical characterisation such as absorption, excitation, emission and lifetime measurements. The absorption spectrum of PG:Ag irradiated with X-rays was decomposed into six Gaussian bands on the basis of its strong analogy with irradiated silver-activated sodium chloride (NaCl:Ag). We confirmed that blue emission peaking at 450 nm was connected with the 270 and 345 nm bands of the excitation spectrum, while orange emission peaking at 560 nm was associated with the 308 nm excitation band. Each band of the excitation spectrum was in turn attributed to an Ag 2 + , Ag 0 or Ag 2+ centre by analogy with the RPL of NaCl:Ag. The excited-state lifetimes for each emissive process were also determined for different X-ray doses. In conclusion, we determined that both blue and orange emissions result from radiation-induced (rather than intrinsic) properties in the range of 1.22 -24.5 Gy.
