The influence of silver-ion doping using ion implantation on the luminescence properties of Er–Yb silicate glasses

THE EFFECT OF ZINC CONTENT ON THE ENHANCEMENT Er3+-Yb3+ LUMINESCENCE PROPERTIES IN THE SILICATE GLASS MATRIX

“…% of Ag, the luminescence intensity increased multiple times in comparison with implantation, where the concentration of Ag was approximately 1 %. These results have confirmed our previous results [12,14], where the discussion of the luminescence-enhancement mechanism was mentioned.…”

“…Silverion implantation was performed in collaboration with the Helmholtz-Zentrum Dresden Rossendorf, Germany, on a Tandetron accelerator. The energy of the implanted Ag + ions was 1.2 MeV or 1.7 MeV using an ion fluence of 1 × 10 16 cm −2 according [12]. The ion-exchange process proceeded as follows: before the process, the clean glass substrate was tempered.…”

“…According to [12], the silver depth profiles were predicted by SRIM simulation. Since the density of the prepared glasses was almost the same as in [12], the R p was about 480 nm (∆R p about 124 nm) for the fluence of 1.2 MeV and about 700 nm (∆R p about 168 nm) for the fluence 1.7 MeV.…”

“…This can be done by the presence of silver in glass matrix. Possible mechanism of this phenomenon can be surface plasmon resonance (SPR) of silver metal nanoparticles (Ns), but it has been shown that this effect can also be observed in glasses containing silver present in the oxidation state +I [11,12].…”

“…We also concentrated to the oxidation state of doped elements, changes in glass matrix caused by presence of zinc and by doping process of silver, coordination number of dopants in resulting arrangement of glass matrix and their influence on the resulting optical and luminescence properties. [6,7,12], and zinc oxide substituted for silica oxide. The glasses were synthesised by the standard melting process, which had been designed to achieve the desired optical homogeneity, at a temperature of 1550°C.…”
