“…The obtained values of the Ω i (I = 2,4,6) parameters follow the same pattern as those observed for different Ho 3+ -doped tellurite glasses and follow the same sequence, namely Ω 2 > Ω 4 > Ω 6 [29]. On the other hand, the sequence is different with Tellurite glasses doped with Pr +3 [24,28].…”

“…The M-2000 Woollam ellipsometer was used to collect the ellipsometric data, and the Perkin Elmer Lambda 900 spectrophotometer was used to capture the transmittance and reflectance spectra. The luminescence decay curves were obtained after a short pulse stimulation delivered by an optical parametric oscillator powered by a third harmonic of a Nd:YAG laser [24]. The photoluminescence spectra were measured using an Optron Dong Woo fluorometer system.…”

The shielding and spectroscopic properties of Pr+3 and Pr3+/Ho3+-codoped tellurite glass were investigated. The intensity parameters (Ω2 = 3.24-, Ω4 = 1.64-, Ω6 = 1.10 × 10−20 cm2) as well as the radiative lifetimes of 3F4 + 5S2 and 5I6 excited states of Ho3+ ions were equal to 301 μs and 3.0 μs, respectively. The former value appears to be much higher than that obtained from the lifetime measurement, indicating the presence of various energy transfer processes. The NIR spectrum of Pr3+/Ho3+-co-doped tellurite glass is dominated by strong Ho3+: 5I6 emission at around 1200 nm, being the result of the energy transfer from Pr3+ to Ho3+ ions. The shielding effectiveness of the prepared glasses showed good performance against high-energy photons. These findings suggest that the prepared glasses could be used in laser technology such as photodynamic therapy (PDT) treatment procedures and as shielding for radiation protection.

“…∆T of SGLu5, SGLu7 and SGLu9 are 172, 180 and 187°C, respectively, which are much larger than that of SG glass. These results suggest that the introduction of Lanthanide cations Lu 3+ with the high field strength in this germanosilicate glass can be a good way to improve the thermal stability, defined as the resistance to the permanent change of properties, particularly, the resistance against crystallization during heating [35]. Compared with the characteristic temperatures in Table 2 and Fig.…”

Structural and fluorescence properties of Ho 3+ /Yb 3+ co-doped germanosilicate glasses have been modified by tailoring the composition using lanthanide additive Lu 2 O 3. Raman spectra and X-ray Photoelectron spectra reveal that the addition of Lu 2 O 3 can change the structure by increasing non-bridging oxygens (NBO) in this glasses. Meanwhile, an improved thermal stability (∆T: from 110 to 187 ˚C) has also been obtained via Lu 3+ 'lanthanide contraction'. Futhermore, the positive effect of changed glass structure gives excellent fluorescence properties by the decreasing cross relaxation process which are proved by the experimental upconversion, near-infrared and mid-infrared fluorescence spectra. Additionally, a double enhancement of a 2.0 µm emission has been achieved successfully in this silica-germanate glass with 7 mol% Lu 3+ addition, which possesses a larger emission cross section (4.41 × 10 −21 cm 2) at 2022 nm. These results indicate that the optimized emission of Ho 3+ for optical fiber laser can be achieved by tuning the glass structure using lanthanide additive Lu 2 O 3 .

“…In other words, the monochromic orange emission originating from the 1 D 2 level of Pr 3þ ions could be controlled by increasing the probability of the 3 P 0 → 1 D 2 NRR process. As matter of fact, there have been relevant reports in this respect on glasses containing Pr 3þ ions [10][11][12][13][14][15] , but there still have been many interesting phenomena waiting for us to discover. In the present paper, we investigate PL properties of zinc strontium phosphate (ZSP) glasses doped with a relatively low Pr 3þ concentration, and discuss the mechanism involved for realizing the monochromatic orange emission.…”

Monochromic orange emission of Pr3+ ions in phosphate glass

2015

Zinc strontium phosphate glasses doped with different trivalent praseodymium ion (Pr 3þ ) concentrations are presented and their photoluminescence properties are investigated upon 442 nm excitation. With the Pr 3þ concentration decreasing, the orange emission of Pr 3þ ( 1 D 2 − 3 H J ) is enhanced steadily at the cost of its blue emission ( 3 P 1;0 − 3 H 4 ). Monochromic orange emission of Pr 3þ ions is obtained when the Pr 3þ doping is reduced to 0.05 mol.%. The mechanism controlling the monochromatic characteristic of Pr 3þ emissions is supposed to be associated with the phonon-aided nonradiative relaxation process of Pr 3þ : 3 P j → 1 D 2 , which depends on the Pr 3þ concentration as well as the phonon energy of the glass matrix. Sodium zinc tellurite and barium gadolinium germinate glasses with the lower phonon energy are used as reference hosts to clarify this mechanism, and the results obtained support this suggestion.
