Aggregation-Induced Emission Features of Organometal Halide Perovskites and Their Fluorescence Probe Applications

---

Organometal hybrid perovskites exhibit tunable absorption and photoluminescence spectra that originate from the adjustable excitons of the self-assembled quantum-well structures. The aggregation-induced emission
(AIE) features of (RNH 3 ) 2 PbI 4 (R = alkyl, C n H 2 n +1 , n = 4, 12, 16, 18) as well as
their reversible photoluminescence response to pH value are demonstrated.This interesting phenomenon correlates with the formation of quantum-well structure, which is a novel AIE mechanism. The temperature sensors based
on organometal hybrid perovskites are also investigated. The combination of high sensitivity (1.3% K −1 ) and good reversibility (>500 cycles) of organometal halide perovskites to temperature in a large temperature range (0–80 °C)
makes them to be versatile systems for the temperature sensor applications. Furthermore, as a proof of concept, the application of organometal hybrid perovskites in 2D spatial imaging and NIR light detection is also presented.
