Journal ArticleDOI

Origin of the red emission in zinc oxide nanophosphors

TL;DR: In this article, a combustion method using zinc nitrate and zinc acetate as precursors and urea as a fuel was used to synthesize zinc oxide nano-phosphors (ZnO NPr).
Journal ArticleDOI

Defect correlated fluorescent quenching and electron phonon coupling in the spectral transition of Eu3+ in CaTiO3 for red emission in display application

TL;DR: In this article, a series of CaTiO3 phosphors doped with trivalent europium (Eu3+) and codoped with potassium (K+) ions were prepared by the solid state reaction method and X-ray diffraction results revealed that the obtained powder phosphors consisted out of a single-phase orthorhombic structure and it also indicated that the incorporation of the dopants/co-dopants did not affect the crystal structure.
Journal ArticleDOI

The energy transfer phenomena and colour tunability in Y2O2S:Eu3+/Dy3+ micro-fibers for white emission in solid state lighting applications

TL;DR: It was demonstrated that with an appropriate tuning of the activator content the Y2O2S:Eu(3+)/Dy(3+) phosphors can exhibit a great potential to act as single-emitting component phosphors for white light emission in solid state lighting technology.
Journal ArticleDOI

Energy Transfer Mechanisms and Optical Thermometry of BaMgF4:Yb3+,Er3+ Phosphor

TL;DR: A two-way versatile approach for the fine-tuning of emission from green to the red region, by varying the dopant concentration and adjusting the pulse width of an infrared laser is demonstrated, demonstrating the potential use of BaMgF4:Yb3+,Er3+ phosphor in an optical thermometer due to its highly sensitive temperature detection ability.
Journal ArticleDOI

Afterglow enhancement with In3 + codoping in CaTiO3:Pr3 + red phosphor

TL;DR: In this paper, a single red emission peak of around 613nm was co-doped with In 3+ to charge compensate in the lattice sites where a trivalent ion Pr 3+ substitutes a divalent Ca 2+ ion.
