Figure 2. Reversible phase transitions among α-, β-, and G-ETP2SbCl5 for recyclable repurposing. (a) The schematic diagram for the reversible phase transitions among α-, β-, and G-ETP2SbCl5; (b) The PL spectra and (c) the corresponding integrated intensities of G-ETP2SbCl5 self-healing for 10 cycles; (d) XRD patterns for the products obtained by the reverse phase transition from G-ETP2SbCl5; (e) Integrated PL intensities of the products by the phase transition between α- and G-ETP2SbCl5 for 10 cycles; (f) PLE and PL spectra of G-ETP2SbCl5 before and after 70 oC heating; (g) Absorption spectra of returned α- and β-ETP2SbCl5. The dashed curve represents the absorption profile of commercial YAG:Ce3+ phosphor; Photographs of (h) pc-LEDs and (i) anti-counterfeiting patterns fabricated by the recycled α- and β-ETP2SbCl5 phosphors.
