Mechanoluminescence is a smart light-emitting phenomenon in which applied mechanical energy is directly converted into photon emissions. In particular, mechanoluminescent materials have shown considerable potential for applications in the fields of energy and sensing. This study thoroughly investigates the mechanoluminescence and long afterglow properties of singly doped and codoped Sr2MgSi2O7(SMSO) with varying concentrations of Eu2+ and Dy3+ ions. Subsequently, a comprehensive analysis of its multimode luminescence properties, including photoluminescence, mechanoluminescence, long afterglow, and X-ray-induced luminescence, is conducted. In addition, the density of states mapping is acquired through first-principles calculations, confirming that the enhanced mechanoluminescence properties of SMSO primarily stem from the deep trap introduced by Dy3+. In contrast to traditional mixing with Polydimethylsiloxane, in this study, the powders are incorporated into optically transparent wood to produce a multiresponse with mechanoluminescence, long afterglow, and X-ray-excited luminescence. This structure is achieved by pretreating natural wood, eliminating lignin, and subsequently modifying the wood to overall modification using various smart phosphors and epoxy resin composites. After natural drying, a multifunctional composite wood structure with diverse luminescence properties is obtained. Owing to its environmental friendliness, sustainability, self-power, and cost-effectiveness, this smart mechanoluminescence wood is anticipated to find extensive applications in construction materials and energy-efficient displays.

调制智能机械发光磷光体用于多刺激响应光学木材
机械发光是一种智能发光现象，其中施加的机械能直接转化为光子发射。特别是，机械发光材料在能源和传感领域显示出巨大的应用潜力。本研究深入研究了具有不同浓度的Eu 2+和Dy 3+离子的单掺杂和共掺杂Sr 2 MgSi 2 O 7 (SMSO) 的机械发光和长余辉特性。随后，对其多模发光特性进行了全面分析，包括光致发光、机械发光、长余辉和X射线诱导发光。此外，通过第一性原理计算获得了态密度图，证实了SMSO增强的机械发光性能主要源于Dy 3+引入的深陷阱。与传统的聚二甲基硅氧烷混合不同，在这项研究中，粉末被掺入光学透明的木材中，产生机械发光、长余辉和 X 射线激发发光的多重响应。这种结构是通过对天然木材进行预处理，消除木质素，然后使用各种智能荧光粉和环氧树脂复合材料对木材进行整体改性来实现的。自然干燥后，得到具有多种发光性能的多功能复合木结构。由于其环保性、可持续性、自供电和成本效益，这种智能机械发光木材有望在建筑材料和节能显示器方面得到广泛应用。
