This paper reports the frequency upconversion and cooperative luminescence in YBO 3: Yb
3+-Er 3+ sample. After cw diode laser excitation, at 980 nm, three clear bands were …

Artificial light source for indoor cultivation has been vastly impeded by the lack of high far red
emitting phosphors. Recently, Mn 4+ activated phosphors were reported to be promising …

Abstract Polycrystalline phosphors YK 3 B 6 O 12: RE 3+(RE= Eu, Ce, Tb) were prepared by
the solid-state synthesis. The single crystal-phases of the samples were confirmed by X-ray …

Terbium doped yttrium borate phosphors have been prepared through solid state mixing
method at 1200° C. The concentration of Tb 3+ ions has been varied in order to optimize the …

The red-emitting phosphor (Y, Gd) BO 3: Eu 3+ was prepared by high temperature ball
milling in order to improve the color purity and decrease the calcining temperature. The …

We explored dual precipitating reagents-assisted Ce-based deep blue-emitting borate and
near-white oxide-based luminescent materials. The first precipitating reagent (aqueous …

In this work, YBO3 phosphors doped with Ln3+ (Ce3+, Tb3+, Eu3+) ions were synthesized
by a facile hydrothermal method using high temperature and high pressure environment …

Abstract Y (2− 0.065− 2x) O 3: Eu 3+ 0.065, xMg 2+, xTi 4+(x= 1.0 mol%, 1.5 mol%, 2.0
mol%, 2.5 mol%, and 3.0 mol%) nanotube arrays were firstly synthesized by the sol–gel …

Abstract YBO 3: Ce 3+, Tb 3+ phosphor was prepared from rare earth oxides and boric acid
by a solid state reaction. The phosphor absorbs near UV light through 4f–5d transitions of …
