Negative thermal expansion (NTE) is a counterintuitive physical phenomenon that the unit
cell volume of material usually contracts instead of expands upon heating. With two …

Abstract Rare earth (RE3+)-doped phosphors generally suffer from thermal quenching, in
which their photoluminescence (PL) intensities decrease at high temperatures. Herein, we …

Over the past several decades, research on anomalous thermal expansion materials has
been rapidly growing, and increasing numbers of compounds exhibiting negative thermal …

For oxides, controlling the concentration of oxygen vacancy is a useful way to optimize their
functional properties. However, when it comes to the field of negative thermal expansion …

The coefficient of thermal expansion of ZrMgMo3O12 has been measured and was found to
be extremely close to zero over a wide temperature range including room temperature (α …

Negative-thermal-expansion (NTE) materials violate the common knowledge of “thermal
expansion and cold contraction” in solids and embrace various physical mechanisms. In …

This review presents the history of materials in the A 2 M 3O12 and related ceramic families,
including their unusual thermal expansion and the present understanding of its mechanism …

The Pbcn orthorhombic phase of Y2Mo3O12 has been examined through high-resolution X-
ray powder diffraction (10− 450 K), heat capacity determination (2− 390 K), and differential …

The temperature sensing properties of the Y 2 Mo 3 O 12: Er 3+, Yb 3+ phosphor are
analyzed by using fluorescence intensity ratios (FIRs) of up-conversion (UC) emissions of Er …

Materials with the formula Fe2–x Y x Mo3O12 (x= 0.2, 0.4, 0.5, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, and
1.8) have been synthesized, and their structures, phase transitions, hygroscopicity, and …
