摘要

Abstract

In the era of smart agriculture

the precise labeling and recording of growth information in plants pose challenges for modern agricultural production. This study introduces strontium aluminate particles coated with H

as luminescent labels capable of spatial embedding within plants for information encoding and storage during growth. The encapsulation with H

imparts stability and enhanced luminescence to SrAl

: Eu

(SAO). Using SAO@H

as a low-damage luminescent label

we implement its delivery into plants through microneedles (MNs) patches. The embedded SAO@H

within plants exhibits sustained and unaltered high signal-to-noise afterglow emission

with luminous intensity remaining at approximately 78% of the original for 27 days. To cater to diverse information recording needs

MNs of various geometric shapes are designed for loading SAO@H

and the luminescent signals in different shapes can be accurately identified through a designed program

the corresponding information can be conveniently viewed on a computer. Additionally

inspired by binary information concepts

MNs patches with specific arrangements of luminescent and non-luminescent points are created

resulting in varied luminescent MNs arrays on leaves. An advanced camera system with a tailored program accurately identifies and maps the labels to the corresponding recorded information. These findings showcase the potential of low-damage luminescent labels within plants

paving the way for convenient and widespread storage of plant growth information.
