What is Size‐Controllable Synthesis of Submicro Spherical Yttrium Carbonate and In Situ Doping of Europium to Prepare Y2O3: Eu3+ Phosphor about?

In this work size controllable spherical yttrium carbonate powders with D 50 in range from 225 to 743 nm were synthesized from Y(NO 3 ) 3 •6H 2 O and urea. With the rise of the concentration ratio of urea/Y 3+ , temperature and extension of aging time, diameter of yttrium carbonate spheres increased, when the urea/Y 3+ was 40: 1 and aged for 4 h at 90 o C, the D 50 of synthesized powder which had been determined as Y(OH)CO 3 •1.3H 2 O had the largest D 50 of 743 nm with (D 90 -D 10 )/2D 50 of 0.22. After decomposition, the D 50 of formed Y 2 O 3 decreased to 632 nm, the (D 90 -D 10 )/2D 50 was 0.24, and the D 50 of Y 2 O 3 was range of 126-632 nm. Then 6 mol. % Eu 3+ was homogeneously doped into Y(OH)CO 3 •1.3H 2 O and Y 2 O 3 : Eu 3+ spherical powder was obtained after roasting, which exhibits a strong emission peak at 613 nm. The developed synthetic method and the obtained size controllable spherical Y(OH)CO 3 •1.3H 2 O, Y 2 O 3 and Y 2 O 3 : Eu 3+ with a uniform size distribution, own various potential applications.
