Spectral and thermal properties of Dy3+-doped NaGdTiO4 phosphors

Orange-Reddish Light Emitting Phosphor GdVO4:Sm3+ Prepared by Solution Combustion Synthesis

“…If rare earth ions occupy several di erent sites in host lattices, they can generate several di erent luminescent centers which lead to a multiexponential behavior [29]. Tian et al [30] explained that, in Dy 3+ -doped bulk GdVO 4 :Dy phosphors, the energy transfers mainly happen between Dy 3+ ions [31,32]. In the case of nanoparticles, the energy transfer starting from the luminescent level can be more complicated, since the defects, which can act as quenching centers, in nanoparticles are more plenteous than those in bulk phosphors [29,31,33].…”

Effects of Er 3+ concentration on down-/up-conversion luminescence and temperature sensing properties in NaGdTiO 4 : Er 3+ /Yb 3+ phosphors

“…Layered perovskite titanates complex oxides ARETiO 4 (A=Na, K) have been proven to be a good hosts due to their typical two-dimensional structures and good chemical and physical stabilities [7]. Recently, a series of Er 3+ , Dy 3+ doped NaGdTiO 4 phosphors have been synthesized by the high temperature solid state reaction in our group, the results indicate that phosphors have high luminescent efficiencies and potential application in white light emitting diodes [15,16]. However, very little investigations on the up-conversion luminescence of Er 3+ in ARETiO 4 have been reported, not to mention the influence of Er 3+ concentration on the up-conversion luminescence and temperature sensing properties.…”

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

“…Thus, the yellow-to-blue (Y/B) intensity ratio can be significantly different in different lattices, which to a large extent determines the device potentialities of Dy 3+ -doped materials. As an example, materials with appropriate (Y/B) ratio can be utilized for interesting white light generation [14][15][16]. In the present study, high (Y/B) ratio is desirable.…”
