Transforming mechanical energy into light demonstrates promising applications in terms of visual mechanical sensing. In this work, we synthesized the phosphor CaZnOS:Tb3+, Sm3+, which exhibited intense and tunable multicolor mechanoluminescence without pre-irradiation. Intense green ML materials were obtained by doping Tb3+ with different concentrations. Tunable multicolor mechanoluminescence (such as green, yellow-green, and orange-red) could be realized by combining green emission (about 542 nm), attributed to Tb3+, and red emission (about 600 nm) generated from the Sm3+ in the CaZnOS substrate. The tunable multicolor ML materials CaZnOS:Tb3+, Sm3+ exhibited intense luminance and recoverable mechanoluminescence when responding to mechanical stimulation. Benefiting from the excellent ML performance and multicolor tunability in CaZnOS:Tb3+, Sm3+, we mixed the phosphor with PDMS and a curing agent to explore its practical application. An application for visual mechanical sensing was designed for handwriting identification. By taking a time-lapsed shot while writing, we easily obtained images of the writer\u2019s handwriting. The images of the ML intensity were acquired by using specific software to transform the shooting data. We could easily distinguish people\u2019s handwriting through analyzing the different ML performances.<\/jats:p>","DOI":"10.3390\/nano14151279","type":"journal-article","created":{"date-parts":[[2024,7,30]],"date-time":"2024-07-30T11:11:25Z","timestamp":1722337885000},"page":"1279","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Achieving Tunable Mechanoluminescence in CaZnOS:Tb3+, Sm3+ for Multicolor Stress Sensing"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6393-7271","authenticated-orcid":false,"given":"Wenqi","family":"Wang","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zihui","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziying","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhizhi","family":"Xiang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenbin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sixia","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingjin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weisheng","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Qinghai Normal University, Xining 810008, China"},{"name":"Qinghai Key Laboratory of Advanced Technology and Application of Environmental Functional Materials, Xining 810016, China"},{"name":"Key Laboratory of Nonferrous Metals Chemistry and Resources Utilization of Gansu Province and State Key Laboratory of Applied Organic Chemistry, College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2673","DOI":"10.1038\/s41467-024-46900-w","article-title":"Quantifying the Interfacial Triboelectricity in Inorganic-organic Composite Mechanoluminescent Materials","volume":"15","author":"Pan","year":"2024","journal-title":"Nat.
