“…This spectral shape is consistent with Cu-ion-doped glasses reported previously, although the positions and broadness of peaks have been found to change with the base glass composition [31,32]. Homogeneity of the glass was measured on a centimeter scale by collecting the spectrum for each SRM 2943 sample in both a normal and a raised (0.5 cm) position and by comparing them.…”

a b s t r a c tStandard Reference Material (SRM) 2943 is a cuvette-shaped, Cu-ion-doped glass, recommended for use for relative spectral correction of emission and day-to-day performance verification of steady-state fluorescence spectrometers. Properties of this standard that influence its effective use or contribute to the uncertainty in its certified emission spectrum were explored here. These properties include its photostability, absorbance, dissolution rate in water, anisotropy and temperature coefficient of fluorescence intensity. The expanded uncertainties in the certified spectrum are about 5% around the peak maximum at 446 nm, using an excitation wavelength of 330 nm. SRM 2943 can replace SRM 936a quinine sulfate dihydrate, which is no longer sold by NIST, for many applications, as it covers the same spectral range. SRM 2943 is significantly more photostable than organic dyes, but unlike the other fluorescent glass SRMs in this series, it does photodegrade gradually under lamp-based excitation.

“…Similar observations in form of Ti 4+ -F --Ti 3+ charge transfer were also reported earlier in reduced fluorophosphate glass which contained both the Ti 3+ and Ti 4+ ions (Fuxi 1992). Park and Webb (1972) as well as Annapurna et al (2000) studied the UV-excitation of Cu + ion from 3d 10 configuration to 3d 9 4s 1 and reported the fluorescent transition as the phonon assisted greenish blue emission the broader visible bands for which at around 500 nm were attributed due to spin forbidden transition from excited 3 Eg (3d 9 4s 1 ) → 1 Ag (3d 10 ) ground level in phosphate and zinc borosilicate glasses.…”

Optical absorption and fluorescent behaviour of titanium ions in silicate glasses

Titanium in normal melting conditions in air atmosphere present as Ti 4+ ion in basic silicate glasses exhibited an ultraviolet cutoff in silicate glasses, viz. soda-magnesia-silica, soda-magnesia-limesilica and soda-lime-silica glasses. This indicates that Ti 4+ ion can be a good replacement for Ce 4+ ion in producing UV-absorbing silicate glasses for commercial applications. The wavelength maxima at which the infinite absorption takes place in glasses was found to be around 310 nm against Ti-free blank glass in UV-region. The mechanism of electronic transition from O 2ligands to Ti 4+ ion was suggested as L → → M charge transfer. The low energy tails of the ultraviolet cutoff were found to obey Urbach's rule in the optical range 360-500 nm. The fluorescence spectra of these glasses were also studied and based on the radiative fluorescent properties it was suggested that the soda-lime-silica glass containing Ti 4+ ion with greater emission crosssection would emit a better fluorescence than the corresponding soda-magnesia-lime-silica and sodamagnesia-silica glasses. The shift of emission wavelengths maxima towards longer wavelength in titania introduced silicate glasses was observed on replacement of MgO by CaO which may be attributed due to an increase in basicity of the glass system.

“…Silicate glass is of special interest due to its improved properties, such as higher diaphaneity, better processibility, greater chemical stability, increased hardness, etc. [4][5][6][7][8][9]. There are many methods to prepare glass materials, such as sol-gel method, solid-state reaction, microwave method, and hydrothermal synthesis.…”

“…Several researchers have used the solid-state method to prepare phosphorescence glass of zinc borosilicate [5][6][7][8][9], but the reaction temperature, which was required 1400°C above, was so high that a great deal of energy was expended, and the homogeneity degree of components was not better than the sol-gel method, which may produce negative effect to the phosphorescence property of materials, because of concentration quenching. Accordingly, the purpose of this study is to synthesize a Mn 2+ -doped zinc borosilicate (ZBSM) glass thin film by heat treating a gel film that was prepared by the sol-gel dip-coating method and attribute the characters of the luminescence property, traps distribution, and glass structure of ZBSM glass films.…”

Mn 2+ -doped zinc borosilicate (ZBSM) glass thin films were first synthesized by sol-gel method. In the experiment, a thin gel film was deposited onto quartz glass substrates by dip-coating method and then heat-treated to form a Mn 2+ -doped zinc borosilicate glass thin film. Long lasting phosphorescence (LLP) and photo-stimulated long lasting phosphorescence (PSLLP) were found in the film sample. According to fluorescence spectra, LLP emission spectra, and PSLLP emission spectra, both LLP and PSLLP emissions are attributed to the energy level transition of 4 E g → 4 A 1g from Mn 2+ . Both the phosphorescence intensity decay curves contain a fast decay component and another slow decay one. The thermoluminescence (TL) spectra show that the sample has two kinds of traps at least and their energy level values are about 0.8 eV and 1.02 eV, which could be estimated by the Randall and Willcins formula. The infrared absorption spectra (IR) consist of characteristic vibration bands of Si-O-Si, Si-O-Zn, B-O in [BO 3 ], B-O group, and Zn-O in [ZnO 4 ]. Moreover, image storage and logical operation of the ZBSM film were carried out successfully through an experiment analogues of optical storage.
