Abstract Mechanoluminescence materials that emit light under mechanical stimulation have attracted widespread attention in sensing, anti-counterfeiting and imaging applications. In this study, a series of novel Sr1-xBixZnSO (0.001≤x≤0.1) samples were synthesized by the method of high temperature solid-state reaction. It is worth noting that the distortion degree of SrO3S3 octahedron was increased with increasing Bi3+ concentration, and the color manipulated Sr1-xBixZnSO which can emit different photoluminescence (blue to dark blue and finally red) and mechanoluminescence (orange to red) colors are obtained. Moreover, the deep traps can stably store and provide electronic supplement to shallow traps released under mechanical stimulated. Therefore, devices made of SrZnSO: Bi3+ phosphor and polydimethylsiloxane (PDMS) can be used as thermo-mechano-opto three-mode anti-counterfeiting. The ML intensity is linear to the external load, can be utilized for stress sensing or imaging.

Important Intermediate

Layered potassium titanate is an important intermediate in preparing titania nanosheets. Three methods including method of potassium stearate, method of stearic acid and method of high-temperature solid-state reaction were used to produce layered potassium titanate in this paper. XRD and SEM were used to characterize the crystal structure and shape. The result of experiments showed that method of potassium stearate was the most effective way to prepare the layered potassium titanate.

Effective Energy Transfer

A series of single-phase Sr5(PO4)3F: Eu2+, Tb3+, Na+ phosphors have been synthesized by high temperature solid-state reaction. The photoluminescence excitation and emission spectra, concentration effect and energy transfer from Eu2+ to Tb3+ are investigated in detail. The work shows that there is an effective energy transfer from Eu2+ to Tb3+, where Eu2+ reveals an intense excitation band from 280 nm to 400 nm, matching well with the emission of n-UV chips, and Tb3+ emits an intense green emitting light.
