Spectroscopic studies of Sm3+ and Eu3+ co-doped lithium borate glass

Optical spectroscopy of Li2B4O7, CaB4O7 and LiCaBO3 borate glasses doped with europium

“…Thus, the emission and luminescence excitation spectra also testify that the europium impurity is incorporated in the Li 2 ions. This agrees well with the data known for the Eu-doped lithium tetraborate crystal [22], the lithium tetraborate glass [31], the lithium borate glasses [20,23,43] and the other borate glasses [24,44,45]. However, the above result does not correlate with the findings for the Eu-doped Li 2 B 4 O 7 [31] and SrB 4 O 7 [29] crystals, the lithium borate glasses [21] and some other borate glasses [28,30].…”

“…reveal high luminescence efficiencies in various host materials and the emission in a broad enough spectral range. They are widely used as activator centres in different laser, luminescent and scintillate materials [18,19], including Eu-doped borate crystals and glasses such as Li 2 B 4 O 7 [13,14,[20][21][22][23], SrB 4 O 7 [24,25] and some others [26,27]. One can also notice that crystalline and glassy (or vitreous) oxide compounds are efficient luminescent materials for the 'orange-red' and 'violetblue' spectral regions, when being activated with Eu 3+ and Eu 2+ ions, respectively.…”

“…Up to now the optical and luminescent properties of crystalline and glassy Eu-doped borate compounds with different chemical compositions have been extensively investigated in a number of works [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Let us remind of the main results.…”

Photoluminescence Characteristic of Magnesium Boro-Tellurite doped Eu3+ Ceramic

“…These ceramic can be fabricated at lower cost and speedy processes in a large variety of sizes and shapes (Lupei et al 2005;Mohr et al 2008). Borate has been studied extensively due to the physical properties like low melting point, high thermal stability and good solubility (Elfayoumi et al 2010). …”

Luminescence properties of novel Sm3+, Dy3+ doped LaMoBO6 phosphors

“…Recently, the development of rare earth (RE) ions activated novel luminescent materials have attracted more attention due to their potential applications in different optical display systems [2][3][4][5][6][7][8][9]. Because the 4f electrons of RE ions are shielded by the outer 5s and 5p electrons, the intra-4f emission spectra of RE ions are characterized by narrow lines with high color purity.…”
