The luminescence characteristics of Te-and Bi-doped glasses and glass-ceramics were investigated and the origin of coloration and near infrared luminescence was discussed. The colorations of these glasses and glass-ceramics might be due to the elemental clustering, such as Te 2 Te 2 and Bi 2 Bi 2 . The broad near infrared NIR luminescence can be detected in Te-and Bi-doped glasses and glass-ceramics. The electron spin resonance ESR signal at Ŏ ŋ2.0 was observed in Te-and Bi-doped glasses and glass-ceramics, which exhibit NIR luminescence, and therefore this ESR signal is strongly related to the NIR luminescence. The ESR signal at Ŏ ŋ2.0 might be derived from molecular ions of Te and Bi, Te 2 and Bi 2 . Consequently, it is suggested that the broad NIR luminescence of Te-and Bi-doped glass and glass-ceramics are most likely to be caused by elemental clustering, such as Te 2 Te 2 and Bi 2 Bi 2 .

“…Besides, as the development of the WDM technology and the miniaturization of fiber amplifier, it needs to improve unit length gain. Therefore, developing the non-silica based EDFA with broad amplifying bandwidth and high signal gain per unit length, and directly realizing the seamless amplification of (C+L)-band (1530~1610nm) region has a very important practical significance to the capacity expansion and integration of WDM communication system [4][5][6][7][8].…”

Abstract. Er 3+-doped Li 2 O-SrO-ZnO-Bi 2 O 3 (LSZB) glasses that are suitable for optical amplifier applications have been fabricated through the conventional melt-quenching method, and the spectroscopic properties of Er 3+ in the glasses were characterized. The density, the refractive indices, the optical absorption, the Judd-Ofelt parameters  t , and the spontaneous transition probabilities of the glasses were measured and calculated. The Raman spectrum shows three strong peaks at 255, 382, and 491cm -1 . The emission peak from the Er 3+ : 4 I 13/2 → 4 I 15/2 transition locates around 1.53-µm with a full width at half maximum (FWHM) of ~78 nm. The theory lifetime of the 4 I 13/2 level is ~2.85ms. The emission cross section is estimated to be ~9.76×10 -21 cm 2 , which is larger than those of silicate glasses. In sum, the above results indicate that the LS ZB glass is a promising host material for applications in optical amplifiers.

“…The erbium ion doped silica-based glasses can provide a narrow emission and hence a narrow gain spectrum around 1.55µm . [1][2][3][4] Among the oxide glasses, heavy metal-oxide glasses are highly transparent in the near-infrared (NIR) regions. A heavy metal-oxide glass system as NLG does not contain any traditional glass-form oxide, such as silicon oxide.…”

Abstract-Erbium ion doped sodium lanthanum gallate glasses (Na 2 O-La 2 O 3 -Ga 2 O 3 or NLG) which are suitable for use in optical waveguide devices has been fabricated and characterized. The density, the refractive indexes, the absorption and luminescence spectra along with the luminescence decay time were measured. Using the experimental oscillator strengths, the Judd-Ofelt intensity parameters Ω t were determined, and some important radiative properties were calculated. The emission peak of the 4 I 13/2 → 4 I 15/2 transition is at the 1.53-µm wavelength. The full-width at half-maximum (FWHM) bandwidth is 38 nm, which is larger than that of Er 3+ -doped Ge/P silicate glasses (24.7nm), and comparable to that of Er 3+ -doped Al/P silicate glasses (43.3nm). The lifetime of the 4 I 13/2 level is 7.03ms and the quantum efficiency is ~100%. The results show that the NLG glass is an excellent host material for applications in fiber amplifiers and waveguide lasers.
