TL;DR: In this paper, a promising alternative of photocatalysis where the strained state of a piezoelectric material is exploited for electrochemical surface reactions under dark conditions is discussed.
Journal ArticleDOI

Photoluminescence and thermoluminescence characterization of Eu3+- and Dy3+ -activated Ca3(PO4)2 phosphor

TL;DR: In this paper, the photoluminescence and thermolumine properties of rare earth-doped polycrystalline Ca3(PO4)2:Eu, Ca3PO4:Dy, CaSO4: Dy and Ca3 PO4 2:DY lattice sites were studied for their X-ray diffraction, thermoluminance (TL) and photolumeinescence (PL) characteristics.
Journal ArticleDOI

White light emitting MgAl2O4:Dy3+,Eu3+ nanophosphor for multifunctional applications.

TL;DR: Detailed investigation of PL properties reveals that Eu3+ ions can be well sensitized by Dy3+ under near-ultraviolet excitation of 351 nm, which indicates that the obtained nanophosphors are highly promising for utilizing in WLED based solid state lighting and self-referencing ratiometric temperature sensor applications.
Journal ArticleDOI

Recent advancements in solid–liquid triboelectric nanogenerators for energy harvesting and self-powered applications

TL;DR: Recent progress in the development of S-L TENGs is reviewed for the first time in terms of the different properties of solid and liquid contact materials along with their respective applications.
