Interfacial reactions drive all elemental cycling on Earth and play pivotal roles in human
activities such as agriculture, water purification, energy production and storage …

Nanoparticle assembly and attachment are common pathways of crystal growth by which
particles organize into larger scale materials with hierarchical structure and long-range …

Crystal dissolution, which is a fundamental process in both natural and technological
settings, has been predominately viewed as a process of ion-by-ion detachment into a …

Phase transition of the polymorphs is critical for controlled synthesis and property
modulation of functional materials. Upconversion emissions from an efficient hexagonal …

Solution crystallization of materials ranging from simple salts to complex supramolecular
assemblies has long been viewed through the lens of classical nucleation and growth …

Two series of β-NaYF4: Ln3+ nanoparticles (Ln= La–Nd, Sm–Lu) containing 20 at.% and 40
at.% of Ln3+ with well-defined morphology and size were synthesized via a facile citric-acid …

In this work, monodisperse β-NaLuF 4: Yb, Er microcrystals with intense upconversion
emission were synthesized via a modified hydrothermal method. With the increase of …

Internal OH–defects always cause significant depletion of excitation energy for low
upconversion efficiency; however, preventing the incorporation of OH–into the crystal lattice …

Conventional luminescent materials generally exhibit uni-color and transient emission under
UV excitation, which makes them mediocre in the field of anti-counterfeiting. The high-level …

Uranium–cerium oxide solid solutions, U1− xCexO2+ δ· nH2O, were prepared through
hydrothermal conversion of mixed U (IV)–Ce (III) oxalate precursors, cerium being used as a …
