We present a systematic decay analysis of four sulfide phosphors, namely SrS: Eu 2+, CaAl
2 S 4: Eu 2+, KGaS 2: Eu 2+, and NaBaAlS 3: Eu 2+. In SrS and NaBaAlS 3, there is only …

Herein, a series of novel long afterglow nanophosphors BaYAl3O7: Eu2+, Nd3+ was
synthesized by the combustion method. The investigation encompassed the characterization …

Increasing demand for effective energy conversion materials and devices has renewed
interest in semiconductors comprised of earth-abundant and biocompatible elements …

The persistent luminescence (PersL) materials Ca 2 Sb 2 O 7: Pr 3+ were prepared by
traditional high-temperature solid-state method. We systematically investigated the crystal …

Defects in phosphors affect not only luminescence intensity but also emission peak width,
decay time, and afterglow. The green phosphor β-SiAlON: Eu 2+ exhibits the green emission …

The red persistent luminescence phosphors SrS: Eu x 2+, Pr y 3+(x= 0∼ 0.001, y= 0∼
0.003) were synthesized by the solid-state reaction method in a weak reducing atmosphere …

Red photostimulated luminescence (PSL) at 650 nm appears under the excitation by using
an infrared (IR) light-emitting diode at 940 nm in CaS: Eu 2+ afterglow phosphors. The effect …

In afterglow phosphors, luminescence appears and can be observed with the naked eye for
minutes to hours or more, even after photoexcitation ceases. Red afterglow and …

The allure of long-afterglow materials lies in their ability to emit light for extended durations,
ranging from minutes to even hours, after being exposed to external energy sources such as …

Persistent phosphors are very demanding materials nowadays owing to their various
applications. The emission wavelength determines the color of the emission. An activator …
