Recently, trivalent chromium ion doped phosphors have exhibited significant application potential in broadband near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs). However, developing an NIR phosphor with both broad emission bandwidth and excellent luminescence thermal stability is still a great challenge. Here, we demonstrate phosphor, ScF3:Cr3+, which can fulfill conditions simultaneously. The prepared show the range of 700 to 1100 nm, full width at half-maximum (FWHM)...
Functional phosphors with shortwave infrared (SWIR) persistent luminescence have attracted an ever-increasing interest from scientists owning to the self-sustainable emission for deeper tissue penetration, real-time monitoring, and nondestructive analysis. In this work, we report first time on broad-band wavelength-tunable SWIR photochromism properties of divalent nickel-doped yttrium aluminum gallium garnet solid solutions. The crystal-field-driven superbroad band within wavelength region,...
An ultra-high external quantum efficiency (EQE ≈ 49.4%) is achieved by substituting Ta 5+ with Nb in GaTa 1− y O 4 :Cr 3+ phosphor.
Abstract The improvement of high‐performance narrow‐band green phosphors in backlight display applications is still a major challenge. Based on the UCr 4 C type oxide phosphor, Rb 3 M(Li SiO ) :Eu 2+ (M = or Na) are studied different luminous positions. Benefiting from replacement by Na, change local environment crystal structure Na(Li (R NLSO:Eu leads to decrease Stokes shift, which improves quantum efficiency. Moreover, enhances structural rigidity, makes thermal and chemical stability...
The synthetic fluorescent phosphor has a wide FWHM, which realized the application of non-destructive detection.
