For the first time, Mimosa pudica (M pudica) plant extract was used as a mediator to synthesize Li⁺ (0.1–0.5 mol %) codoped tetragonal BiOCl:Tb³⁺_{0.5 mol %} nanophosphors by the conventional phytosynthesis route. Surface morphological studies confirmed the micro flower like morphology with different petals arrangement. The conduction band and valence band edges were used to realize the effect of codopant on the electronic structure of BiOCl:Tb³⁺_0.5 host. The value of valence band increases from 3.60 to 3.69 eV. Photoluminescence (PL) spectra exhibit characteristic luminescence ⁵D₄ →⁷F_J (J = 0–6) of Tb³⁺ ions. BiOCl:Tb³⁺_0.5:Li⁺ (0.1–0.5 mol %) was good luminescent media for the fabrication of artificial green light in white LEDs and solid state display. Judd-Ofelt theory was used to analyze various radiative properties. Finger Prints dusted by BiOCl:Tb³⁺_0.5:Li⁺ (0.3 mol %) NPs exhibit clear and bright images under UV 254 nm light helpful for identification for individuals.

首次将含羞草（Mimosa pudica）植物提取物用作介体，通过常规植物合成途径合成了Li ⁺（0.1–0.5 mol％）共掺杂的四方BiOCl：Tb ³⁺ _{0.5 mol％}纳米磷光体。表面形态学研究证实不同花瓣排列的微花状形态。使用导带和价带边缘来实现共掺杂对BiOCl：Tb ³⁺ _0.5主体电子结构的影响。价带的值从3.60 eV增加到3.69 eV。光致发光（PL）光谱表现出Tb的特征性发光⁵ D ₄ → ⁷ F _J（J = 0-6）³⁺离子。BiOCl：Tb ³⁺ _0.5：Li ⁺（0.1–0.5 mol％）是用于在白色LED和固态显示器中制造人造绿光的良好发光介质。Judd-Ofelt理论用于分析各种辐射特性。由BiOCl：Tb ³⁺ _0.5：Li ⁺（0.3 mol％）撒粉的指纹在254 nm紫外线下显示出清晰明亮的图像，有助于个人识别。
