“…Even if the formation mechanisms of hole and electron traps are different, in all the irradiated cases, the 460 and 620 nm peak observed in the emission spectrum is believed to be due to aggregation of Ag 0 and Ag + ions which have possibly generated additional chemically stable clusters Ag m x+ such as Ag 2 + , Ag 3 2+ [9]. All these observations are consistent with a decrease of the emission of isolated silver ions showing that silver is definitely acting as the electron trap [16]. There is no emission peak observed for 3.5% of Ag-doped phosphate glass sample before γ-irradiation at 460 nm, which means there is no mechanism of hole and electron traps occurs and no Ag 0 centreswere producedwithin the glass network.…”

A series of silver-activated phosphate glass was prepared by melt quenching method. The effect of silver nanoparticle addition on the phosphate glass microstructure, composition and chemical characteristics was investigated using x-ray diffraction, fourier transform infrared and photoluminescence spectroscopy. Other physical property such as density was also evaluated. The density increased when the amount of silver ions were increased, due to the enhanced formation of non-bridging oxygen. In this study, we discuss the emission mechanism of two radio-photoluminescence peaks at 460 nm and 620 nm, where the electrons and holes produced by γ-irradiation a re-trapped by Ag + ions to produce Ag 0 and Ag 2+ ions respectively, when the Ag + -doped phosphate glass is exposed to γ-ray. We proposed that an emission mechanism of 460 and 620 nm radio-photoluminescence peaks with these Ag 2+ and Ag 0 ions. Furthermore, a correlation between the investigated properties and glass composition is discussed.Keywords: silver nanoparticle, optical and physical properties, radio-photoluminescence glass dosimeter Abstrak Satu siri gelas argentum-aktif fosfat telah dihasilkan menerusi kaedah peleburan. Kesan penambahan nanobahan argentum ke dalam mikrostruktur gelas fosfat, komposisi dan sifat-sifat kimia dikaji dengan menggunakan pembelauan sinar-X, penjelmaan inframerah Fourier dan spektroskopi pendarcahaya. Sifat fizikal yang lain seperti ketumpatan kacaturut dikaji. Ketumpatan kaca bertambah apabila jumlah ion-ion argentum ditingkatkan, disebabkan oleh peningkatan pembentukan oksigen tanpa-hubung. Dalam kajian ini, kami membincangkan mekanisme pemancaran oleh dua puncak radio-pendarcahaya pada jalur 460 nm dan 620 nm, di mana elektron dan lohong yang terhasil daripada sinar-γ diperangkap oleh ion -ion Ag + seterusnya menghasilkan ionion Ag 0 dan Ag 2+, apabila kaca Ag + -aktif fosfat didedahkan kepada sinar-γ. Kami turut membincangkan mekanisme pemancaran bagi setiap puncak radio-pendarcahaya pada jalur 460 dan 620 nm berdasarkan ion -ion Ag 2+ dan Ag 0 berkenaan. Tambahan lagi, hubung kait antara komposisi kaca dan sifat-sifat kaca yang terhasil turut dibincangkan.Kata kunci: nanobahan argentum, sifat fizikal and optik, dosimeter kaca radio-pendarcahaya ISSN -2506 Irman et al: EFFECT OF SILVER NANOPARTICLE ADDITION ON THE STRUCTURE AND CHARACTERISTICS OF RADIO-PHOTOLUMINESCENCE GLASS DOSIMETER 65Introduction Recent technological applications have generated more interest in the study of glasses especially oxide glasses [1 -6]. Among oxide glasses, phosphate based glasses are particularly attractive due to their ability to accommodate large concentrations of active ions without losing their useful properties of the material [1]. Phosphate glasses are relatively easy to prepare and offers a large range of compositional possibilities, which facilitates in tailoring the physical, chemical and optical properties of interest for specific technological applications [7]. In particular, embedding materials such as metal nanoparticl...

“…It was established from these results that the decomposed six Gaussian bands induced by X-ray irradiation in PG:Ag were, in turn, attributed to Ag + , Ag 3 + or Ag 3 2+ , Ag 2 + , Ag 2+ , Ag 0 and hole-trap centres, respectively. In addition, some similar spectral studies of the silver-related species created after different irradiation have also been reported to clearly attribute these Ag m x+ centres in various glasses (Maurel et al, 2009;Jiménez et al, 2009;Miyamoto et al, 2010). This paper examines the formation and assignment of silver defect centres such as Ag 0 , Ag 2+ and other molecular silver species induced by fs laser pulse irradiation.…”

We have investigated the formation and assignment of silver defect centres such as Ag 0 , Ag 2+ and other molecular silver species induced by femtosecond (fs) laser pulse irradiation. In particular, direct precipitation of silver nanoparticles without heat treatment was demonstrated to clarify the formation kinetics of silver defect centres in a radiophotoluminescent phosphate glass by 250 kHz high repetition rate fs laser pulses. Comparison using X-ray-and fs laser-irradiation methods is also presented.

“…Radiation-induced Ag 0 centres have also been studied to better understand silver nanoparticles in RPL glass dosimeters for X-ray and γ-radiation applications [10][11][12][13][16][17]. In general, silver nanoparticles in PG:Ag are typically prepared through the introduction of Ag + ions into the host, followed by irradiation with low-intensity femtosecond (fs) laser pulses and subsequent heat treatment at a high temperature for several hours [18,19].…”

The direct observation and characterisation of silver nanoparticles or clusters embedded in a Ag + -activated phosphate glass (PG:Ag) was demonstrated. Correlations between the isolated Ag + concentration and X-ray-induced silver species were systematically examined using optical measurements. Evidence of spherical silver nanoparticles or clusters in X-ray-irradiated PG:Ag with sizes ranging from 5 to 30 nm was obtained from the lattice spacings and from energy dispersive X-ray spectroscopy (EDXS) combined with transmission electron microscopy (TEM). Three-dimensional (3D) contour plots using combined excitation-emission spectroscopy (CEES) were also recorded for X-ray-irradiated PG:Ag to allow identification of the complicated spectroscopic features of the sample.
