In this work, we immobilized cadmium selenium sulfur/zinc sulfide (CdSeS/ZnS) quantum dots into polydimethylsiloxane coatings via plasma treatment. We utilized a combination of diffuse reflection and fluorescence of wrinkled structures to indicate changes in the structures. [Display omitted] •Immobilized (CdSeS/ZnS) quantum dots into PDMS coatings via plasma treatment.•Utilized a combination of diffuse reflection and fluorescence of wrinkled structures.•Fluorescence intensity decreased most when strain was 35.29%, incident angle was 15°, and detection angle was 60°.•Developed equations for strain and temperature as a function of fluorescence intensity. Currently, wrinkles are widely used in the fields of wearable electronics, photo-thermal modulation fabrics, fibre-reinforced composite waterproof, and antimicrobial fabrics. However, human eyes cannot detect micro- or nano-wrinkled structures. Hence, we utilized fluorescence to monitor dynamic wrinkled structures. In this study, we immobilized cadmium selenium sulfur/zinc sulfide (CdSeS/ZnS) quantum dots into polydimethylsiloxane coatings via plasma treatment. We utilized a combination of the diffuse reflection and fluorescence of wrinkled structures to examine changes in the structures. Strain modulation was employed to establish the correlation of incidence and detection angles with parameters corresponding to wrinkled structures, allowing independent modulation of fluorescence intensity changes. The fluorescence intensity decreased most significantly when the strain was 35.29 %, the incident angle was 15°, and the detection angle was 60°. Additionally, we separately established linear equations to describe the relations between strain, temperature as well as fluorescence intensity function, providing guidance for comprehending the fluorescence intensity and dynamic wrinkles.
