Multimodal luminescence involves color-tunable and wavelength manageable photon emissions upon variable pathways in response to different external stimuli, which provides clear visualization high-level confidentiality for information encryption technologies. Integrating multimodal into a single matrix is regarded as feasible strategy but remains big challenge. In this work, (photoluminescence, persistent luminescence, upconversion thermally stimulated luminescence) multicolor (green, yellow, orange, pink red) achieved CaWO4:Yb3+,Er3+,Eu3+ phosphor by employing an interplay of traps rare earth emission centers. Bright wide color gamut dynamically thermal disturbance light illumination, further allows on-demand manipulation space time dimensions. The compatible coexistence multiple emissive centers together with abundant photoactive contributes the excellent integration calcium tungstate. This work good example integrating one indicates potential advanced applications.
