Spectroscopic study of Dy3+ and Dy3+/Yb3+ ions co-doped in barium fluoroborate glass

Spectroscopic and photoluminescence properties of Dy3+-doped lead tungsten tellurite glasses for laser materials

“…(3)-(6), in order to predict the efficient luminescence Table 3 are found to be in good agreement with those reported in literature [7,21,23,28,29]. The branching ratios and stimulated emission cross-sections are the important laser parameters which predict the luminescence efficiency of host material.…”

“…Several glass matrices such as fluorides, phosphates, borates, fluorophosphates, fluoroborates, fluorozirconates, sulfides, selenides and tellurites have been widely investigated to understand the effect of the host on the lasing properties of the rare-earth ions [1][2][3][4][5][6][7][8][9][10][11]. Recently, photoluminescence properties of tellurite and heavy metal oxide glasses doped with rare earth ions have been studied due to their low phonon energies, high refractive indices and good rare-earth ions solubility [12].…”

Effect of Dy3+ ions concentration on optical properties of lead borosilicate glasses for white light emission

“…17 Table 6. From Table 6, it is observed that, the e values of the present glasses are found to be higher than those of other Dy 3+ doped glasses [25,26,[31][32][33]28,[34][35][36].…”

“…The f exp , f cal values for Dy 1.0 :LBS glass are also presented in Table 3. The evaluated Judd-Ofelt intensity parameters of the Dy 1.0 :LBS glass are compared with the earlier reported glasses in Table 4 [15,19,[23][24][25][26][27][28][29]. From Table 4, it observed that the magnitude of Judd-Ofelt intensity parameters follow the trend as ˝2 > ˝4 > ˝6.…”

Excitability of high-energy ultraviolet radiation for Dy3+ in antimony phosphate glasses

“…7. The radiative transitions belonging to the 4f 9 electronic configurations can be analyzed by the JuddOfelt (J-O) theory based on the absorption of Dy 3+ [61][62][63][64][65][66][67][68][69]. J-O intensity parameters Ω t (t = 2, 4, 6) for Dy 3+ in ZASP glasses were calculated to be 5.74 ×10 −20 cm 2 , 1.47 × 10 −20 cm 2 and 1.12 × 10 −20 cm 2 , respectively, and the rootmean-square deviation between the experimental and calculated oscillator strengths was assessed to be 2.3 × 10 −7 , indicating that the fitting process is reliable.…”
