The steady- and transient-state optical properties of the blue and orange radiophotoluminescence (RPL) in Ag-activated phosphate glass were compared.
The dose distributions as a function of the implantation depth were measured in Cs137 and Co60 gamma–ray–irradiated Ag-doped glasses using a time-resolved spectrum technique.
A fluorescent track imaging was demonstrated using a confocal fluorescent microscope for the first time.
