Flexible narrowband near infrared (NIR) photodetectors (PDs) are urgently in demand in the fast-developing era of flexible electronics,due to their crucial roles in various innovative applications.Hence,we designed and synthesized the core-shell structure
Significant developments have been made in the past few decades for lanthanide (Ln) ions doped flu-orosilicate glass-ceramics (Flusi-GCs).As novel generation of luminescence materials with a wide range of applications,Flusi-GCs as a single host combine th
Luminescence ratiometric thermometry based on rare earth (RE) ions has attracted great interest for the potential applications in many fields.But the improvement of the measurement sensitivity and accuracy is significantly restricted due to the small ener
Due to the characteristic emission of phosphors,phosphor-converted LEDs have been employed to provide the requisite light sources for indoor plant growth in the optical agricultural industry.Herein,we prepared a series of Mn2+ co-doped NaSrB5O9∶Dy3+ phosp
Cyan-emitting Ca9NaGd2/3(PO4)7∶Eu2+ phosphors were synthesized via high temperature solid-state route.X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) were used to verify the phase and morphology of the Ca9NaGd2/3(PO4)7∶Eu2+ (CNGP∶Eu2
CaWO4∶xEu3+,yTm3+ crystals were obtained by facile synthesis at low temperature by the microwave-assisted hydrothermal method (MAH).The phase formation,morphology,luminescent properties and energy transfer were investigated.The X-ray diffraction (XRD) res
While the versatile composition of layered double hydroxides (LDHs) allows the introduction of almost any polyvalent cation in their structure,the exchangeable negatively charged ions intercalated between the plates increase their vast range of functional
In this paper,Dy3+ incorporated BaSi2O5 phosphors were synthesized by gel combustion method and char-acterized by X-ray diffraction (XRD).The effects of various heating rates on thermoluminescence (TL) kinetics and glow peak temperatures of Dy3+ incorpora
