Phosphor-converted white light-emitting diodes (pc-WLEDs) with a supreme color rendering index (CRI) remain challenging, particularly due to the limited accessibility of efficient cyan-green-emitting phosphors in 480-520 nm emission range. Herein, novel rare earth-free Ta5+-substituted CsVO3 phosphor that exhibits VO43- charge transfer enabled cyan-green band centered at ∼520 under 370 near UV (n-UV) light is reported an internal quantum efficiency 93.9%. This profile could align well broad-band yellow-orange produce high CRI warm light. Such spectra are achieved by incorporating Cs+ ions into Rb3V5O14 system, which tunes from red orange and eventually yellow. Furthermore, absorption Rb3-xCsxV5O14 was followed energy 2p O2- 3d V5+ orbitals, resulting perceived pigment-type colors ranging yellow promising NIR reflectance. When combined strategically, they can be excited n-UV generate well-distributed impressive 89 low temperature (CCT) 4056 K. These findings suggest newly developed vanadates hold promise for use full-spectrum pc-WLEDs.

Multimodal luminescent materials are widely used in noncontact temperature sensors and fluorescent dynamic anticounterfeiting due to their visible persistent luminescence fast optical signal response. To this end, CaY0.99GaO4: 0.01 Bi3+; CaY0.92GaO4: Bi3+, 0.07Eu3+; CaY0.96GaO4: 0.03Er3+ phosphors were prepared using the high-temperature solid-state method. The down-conversion luminescence, up-conversion long mechanical of studied, achieving multicolor luminescence. It was found that 0.07Eu3+ phosphor achieves maximum relative sensitivity 1.49% K-1. These show great potential for applications detection. Through density functional theory electron localization function analysis, multimodal CaYGaO4: Eu3+/Er3+ studied. ion doping leads a decrease band gap induces Jahn-Teller effect, creating lower energy channels accelerate carrier release enhance performance. This is fundamental reason realization human motion Subsequently, novel sensing device detection developed high performance phosphor. properties demonstrated static-dynamic applications. Finally, it stability wide defect states provide new approach sensors, detection, information storage, anticounterfeiting.
