Effect of Bi2O3 on the structural and spectroscopic properties of Sm3+ ions doped sodiumfluoroborate glasses

Optical Spectroscopy and Excited‐State Dynamics of Eu3+‐Doped Bismuth Borate Glasses Containing CuO

“…The band around 702 cm À 1 may be attributed to the BÀ OÀ B bending in bridging oxygens between trigonal BO 3 units, [1] with some contribution from stretching vibrations in BiÀ O bonds. [3] On the other hand, the broad convoluted absorption regions within 770 to 1100 cm À 1 and 1125 to 1400 cm À 1 are indicative of the BÀ O bond stretching vibrations in tetrahedral BO 4 units and trigonal BO 3 units, respectively. [1,3,13] It turns out that the spectra for the 0.1-0.5CuEu glasses appear similar to the undoped host.…”

[1,3,13] It turns out that the spectra for the 0.1-0.5CuEu glasses appear similar to the undoped host. Thus, it is indicated that the basic structural features are not being significantly modified by the co-dopants which are added in relatively small quantities.…”

“…Bismuth borate glasses have gained much attention in the context of light-emitting devices (LEDs) given their eco-friendly nature and the capability for the glasses to be melted at relatively low temperatures (i. e. low-melting character). [1][2][3] For instance, the embedding of Ce:YAG phosphors for such purpose is an aspect of increasing interest due to the pressing challenges of society for utilizing energy more efficiently. [2,[4][5][6] In such context, rare-earth (RE) ions are usually introduced into the glass compositions aiming for an improvement in the color yield of the embodiments employed for white-light generation.…”

Investigations on Structural and Optical Properties of Various Modifier Oxides (MO = ZnO, CdO, BaO, and PbO) Containing Bismuth Borate Lithium Glasses

“…The UE of the BiBLM glasses is smaller than that of other Bismuthate containing glasses. UE of glasses increases from BiBLM1 to BiBLM4 (i.e., 428 to 460 meV), so that it suggests the presence of less disorderliness, minimum defects, and maybe in glasses system compositional changes take place in present glasses [47][48][49][50]. From Table 5 it is noticed that both indirect and direct values follow the trend BiBLM1 > BiBLM2 > BiBLM3 > BiBLM4, also UE follows the reverse trend BiBLM4 > BiBLM3 > BiBLM2 > BiBLM1.…”

Optical and luminescence properties of Li2O Gd2O3MO B2O3Sm2O3 (MO Bi2O3, BaO) glasses

“…Herrera et al [11] study Visible-NIR emission and structural properties of Sm 3+ doped heavy-metal oxide glass with composition B 2 O 3 -PbO-Bi 2 O 3 -GeO 2 to develop tunable laser and optoelectronics devices. Mariyappan et al [12] investigate the effect of Bi 2 O 3 on the structural and spectroscopic properties of Sm 3+ ions doped sodium fluoro-borate glasses for useful gain medium and reddish orange laser applications. Spectroscopic properties of Sm 3+ ions in phosphate and fluorophosphate glasses are investigated by Venkatramu et al [13].…”
