Spectroscopic assessment of Dy3+:LiLa(MoO4)2 crystal as an active medium for all-solid-state direct yellow-emitting lasers

“…The experimental b exp and (Y/B) exp ratio in the Dy 3+ : LiLa(MoO 4 ) 2 crystal are found to be substantially high among the Dy 3+ -doped crystals listed in Table 4, which is consistent with high X 2 parameter. Moreover, b exp matches well with b cal , which reveals the validity of the Judd-Ofelt theory to predict radiative properties; On the other hand, the (Y/B) cal is much larger than the corresponding (Y/B) exp for the most of Dy 3+ -doped hosts ever reported, which also reflect partial inadequacy of the Judd-Ofelt theory for estimating the (Y/B) ratio [17].…”

“…In the present study, high (Y/B) ratio is desirable. As Faoro et al [12] and Bigotta et al [17] pointed out, the (Y/B) ratio is closely related to the X 2 parameter calculated by the Judd-Ofelt theory. Large X 2 parameter gives rise to relatively high values of the (Y/B) ratio and of the total emission probability from the 4 F 9/2 upper laser level, which is advantageous for yellow laser oscillation around 570 nm.…”

“…As the X 2 parameter correlates strongly with the absorption and radiative properties of a material [12,17,23], the X 2 parameters of the Dy 3+ :LiLa(MoO 4 ) 2 crystal are listed in Table 4 and compared with some other Dy 3+ -doped matrices. The X 2 parameters for the Dy 3+ :LiLa(MoO 4 ) 2 crystal are of the same order of magnitude as those of the isostructural Dy 3+ :CaMoO 4 [18] and Dy 3+ : LiGd(MoO 4 ) 2 crystals [23], and to our knowledge much greater than those of any other crystals previously reported (e.g., fluorides, silicates, borates).…”

Synthesis and characterization of YNbTiO6:Dy3+ phosphor

“…E-mail address: wyh@lzu.edu.cn (Y. Wang).in a given host material, it is of great interest and importance to search materials that give intense emission of Dy 3+ . Thus, Dy 3+ doped materials have been intensively studied in recent years, such as KY 3 F 10 :Dy 3+ , LiLuF 4 :Dy 3+[9], Gd 3 Al 5 O 12 :Dy 3+[10], Gd 2 (MoO 4 ) 3 :Dy 3+[11], SnO 2 :Dy 3+[12], Ca 3 La(VO 4 ) 3 :Dy 3+[13] and M 5 (PO 4 ) 3 F:Dy 3+…”
