The trivalent lanthanides have been broadly utilized as emitting centers in persistent luminescence (PersL) materials due to their wide spectral range, which thus attract considerable attention over decades. However, the origin of lanthanides' PersL is still an open question, hindering development excellent phosphors and broad applications. Here, 12 kinds with exception La3+, Lu3+, Pm3+ reported, a mechanism bandgap hosts proposed. According mechanism, excitons transfer recombination energy...
Abstract Developing X-ray scintillators that are water-dispersible, compatible with polymeric matrices, and processable to flexible substrates is an important challenge. Herein, Tb 3+ -doped Na 5 Lu 9 F 32 introduced as scintillating material steady-state light yields of 15,800 photons MeV −1 , which generated nanocrystals on halloysite nanotubes. The obtained product exhibits good water-dispersibility highly sensitive luminescence X-rays. It deposited onto a polyurethane foam afford...
Abstract Photo-crosslinking polymerization stands as a fundamental pillar in the domains of chemistry, biology, and medicine. Yet, prevailing strategies heavily rely on ultraviolet/visible (UV/Vis) light to elicit situ crosslinking. The inherent perils associated with UV radiation, namely potential for DNA damage, coupled limited depth tissue penetration exhibited by UV/Vis light, severely restrict scope photo-crosslinking within living organisms. Although near-infrared has been explored an...
A class of Yb 3+ /Er co‐doped NaY(MoO 4 ) 2 upconversion ( UC phosphors have been successfully synthesized by a facile hydrothermal route with further calcination. The structural properties and the phase composition samples were characterized X‐ray diffraction XRD ). luminescence investigated in detail. Concentration‐dependent studies revealed that optimal was realized for 2% Er 10% ‐doping concentration. Two‐photon excitation mechanism illustrated green enhancement arised from novel...
Abstract Under 971 nm excitation, bright green and red emissions from Yb 3+ /Er co-doped Ba 5 Gd 8 Zn 4 O 21 phosphor can be observed, especially the intense emission in highly doped samples. The experimental results indicate that :Yb , Er emits stronger upconversion luminescence than NaYF under a low excitation power maximum efficiency of 2.7% for was achieved. More significantly, to explain enhanced with dopant concentration, this paper presents possible cross-relaxation process...
Abstract Owing to the forthcoming global energy crisis, search for energy‐saving materials has intensified. Over past two decades, mechanically induced luminescent have received considerable attention as they can convert waste into useful components, instance, conversion from stress light. However, this material features many constraints that limit its widespread application. Herein, a strategy improve mechanoluminescence (ML) of ZnO by embedding it in ZnF 2 :Mn 2+ matrix is introduced. Upon...
Ultraviolet-C (UVC) photons play a key role in many fields such as covert communication, bacterial inactivation, information storage, and encryption. Because the UVC component of solar spectrum is almost absorbed by ozone layer around our earth, there little natural light on earth. Therefore, developing artificial source great significance. The visible-to-UVC upconversion mechanism has been demonstrated to be useful strategy. Here, we introduce system, that is, CaSrSiO4:Pr3+. Under...
Abstract Lanthanide doped nanoparticles (NPs) exhibit tunable X‐ray‐excited optical luminescence and persistent (XEPL), holding broad prospects for applications in display/anti‐counterfeiting X‐ray imaging. The development of effective strategies multi‐dimensional based on lanthanide‐doped fluoride NPs are a constant challenge. Here, core–shell structured NPs, which the heavy metal shell effectively suppresses non‐radiative relaxation simultaneously improve absorption designed fabricated....
Uniform and well-crystallized calcium fluorapatite [Ca5(PO4)3F, FAP] microrods have been successfully synthesized by a facile one-step hydrothermal synthesis method using sodium citrate as the crystal modifier. X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission (TEM), photoluminescence (PL), photoluminescent excitation spectra (PLE) decay studies were employed to characterize samples. The electronic structure orbital population of FAP also determined...
A novel, to the best of our knowledge, optical temperature measurement method is proposed, i.e., persistent luminescence intensity ratio (PLIR) thermometry. The PLIR thermometry relies on micro-sized NaYF4:Pr3+ material that can emit (PersL) uninterruptedly after being charged by x ray irradiation. 3P1→3H5 and 3P0→3H5 PersL transitions, locating separately at ∼ 522 538 nm, have been confirmed follow Boltzmann distribution. emitting this pair lines thus found be a good indicator variation...
Mechanoluminescent materials, which are capable of converting some ignored mechanical stimuli like friction, pressure, and distortion into useful photons, gathering increasing attention nowadays, especially considering that a new round energy crisis is sweeping across the globe. However, wavelength mechanoluminescence (ML) reported so far overlaps seriously with solar spectrum, limiting practical applications mechanoluminescent materials to extent. Here, we report ultraviolet-C (UVC) ML from...
