Electron-Phonon Interaction in Te-Doped (NH₄)₂SnCl₆: Dual-Parameter Optical Thermometry (100–400 K)

Lead-free perovskite variants have emerged as promising candidates due to their self-trapped exciton emission. However, in ASnX₃ systems, facile oxidation of Sn(II) to Sn(IV) yields A₂SnCl₆ vacancy-ordered derivatives. Paradoxically, despite possessing a direct bandg...
