NaLaMo2O8:Yb3+, Er3+ transparent glass ceramics: Up-conversion luminescence and temperature sensitivity property

Dy3+‐ and/or Sm3+‐doped glass–ceramics containing NaGd(MoO4)2 crystalline phase for warm white light applications

“…As the radius of the Dy 3+ ion ( r = 0.91 Å) 78 is similar to the radius of the Gd 3+ ion ( r = 0.94 Å), 79 the introduced Dy 3+ ion is most likely to enter the Gd site in the NaGd(MoO 4 ) 2 crystal. Typically, crystals have lower phonon energy compared to glass 83,84 . The energy of phonons has a significant impact on the luminescence of rare‐earth ions.…”

“…Typically, crystals have lower phonon energy compared to glass. 83,84 The energy of phonons has a significant impact on the luminescence of rare-earth ions. The presence of Dy 3+ ions at lower phonon energy decreases the likelihood of NR transitions, resulting in an increase in luminescence.…”

Manipulating the thermometric behaviors of Er3+/Yb3+/Ho3+-tridoped La2Mo3O12 polychromatic upconverting microparticles via adjusting spatial mode and a sensing strategy

“…26 Chen et al reported that the NaLaMo 2 O 8 :Yb 3+ /Er 3+ phosphors did not only exhibit intense UC emissions, but were also promising luminescent candidates for thermometry. 27 In spite of these exciting achievements, extra investigations are still needed to further carry out the luminescence characterization of rare-earth ion-doped molybdates so as to promote their applications. Currently, the interest in La 2 Mo 3 O 12 (LMO) is increasing and various rareearth ions, such as Tm 3+ , Eu 3+ , Er 3+ , Sm 3+ , etc., [28][29][30] have been introduced into LMO host lattices to synthesize highly efficient luminescent materials.…”
