Enhancement of the luminescent intensity of the green emitting Gd2O2CO3:Tb phosphor

LaPO4:Eu3+, LaPO4:Ce3+, and LaPO4:Ce3+,Tb3+ nanocrystals: Oleic acid assisted solvothermal synthesis, characterization, and luminescent properties

“…Over the past decades, doping is a widely applied process in materials science which involves incorporating appropriate atoms or ions into host lattices to yield hybrid materials with desirable properties and functions [1][2][3][4][5][6][7][8][9]. Recently, a particular emphasis has been placed on the study of rare earth (RE) ions doped compounds due to their large variety of applications [10][11][12][13][14][15][16][17][18].…”

Crystal Structure and Phase Transitions of Gd(CO3)OH Studied by Synchrotron Powder Diffraction

“…Gd compounds have attracted much attention because of their prospective applications, for example, in phosphor materials for large flat display panels 1,2 and as a contrast agent for magnetic-resonance imaging (MRI) in the sciences. [3][4][5][6] Biocompatible amorphous Gd 2 O(CO 3 ) 2 ×H 2 O has been demonstrated to enhance T 1 and to decrease T 2 in nuclear magnetic resonance effects, and thus is an alternative MRI contrast agent.…”

Synthesis and luminescence properties of the lithium-containing lanthanum-oxycarbonate-like borates

“…The green-emitting phosphors Gd 2 O 2 CO 3 :Tb 3 þ and (Gd 0.95 Y 0.05 ) 2 O 2 CO 3 :Tb 3 þ exhibited high relative emission intensity, which was 111% and 131% of that of a commercial LaPO 4 :Ce 3 þ ,Tb 3 þ phosphor, respectively [2,17]. Type II La 2 O 2 CO 3 :Eu 3 þ , Gd 2 O 2 CO 3 :Eu 3 þ , and Y 2 O 2 CO 3 :Eu 3 þ have been synthesized and studied as red phosphors [18].…”

“…Recently, lanthanide hexagonal type-II oxycarbonates attract attention because of their amazing luminescence properties [12][13][14][15][16][17]. The green-emitting phosphors Gd 2 O 2 CO 3 :Tb 3 þ and (Gd 0.95 Y 0.05 ) 2 O 2 CO 3 :Tb 3 þ exhibited high relative emission intensity, which was 111% and 131% of that of a commercial LaPO 4 :Ce 3 þ ,Tb 3 þ phosphor, respectively [2,17].…”
