Stokes Shift in Inorganic Lead Halide Perovskites: Current Status and Perspective

“…44 meV in mixed halides by HI method [62] . Also, a single report about the existence of large Stokes shift of about 290 nm in CsPbI 3 has been reported by S. Gull et al., by modifying the reaction temperature and the amount of injected caesium precursor [63] . Moreover, by doping with manganese, large Stokes shift in the inorganic halide has also been reported.…”

[63] Moreover, by doping with manganese, large Stokes shift in the inorganic halide has also been reported. Qian Wang and co‐workers reported about more than 200 nm Stokes shift for CsPbCl 3 :Mn 2+ with yellow emission synthesized by HI strategy.…”

“…From the synthesis temperature between 95 °C to 160 °C there exist large Stokes shift of 289 nm which reduces with the increment in reaction temperature and vanishes at 170 °C as shown in Figure 4 (d). [63] …”

“…From the synthesis temperature between 95 °C to 160 °C there exist large Stokes shift of 289 nm which reduces with the increment in reaction temperature and vanishes at 170 °C as shown in Figure 4(d). [63] Composition and morphology also contribute equally towards the occurrence of Stokes shift in the inorganic lead halide. Fan Fang et al, synthesized inorganic lead halide perovskites by different methods as shown in Figure 4(e-g).…”

Synthesis of cesium lead halide perovskite/zinc oxide (CsPbX3/ZnO, X= Br, I) as heterostructure photocatalyst with improved activity for heavy metal degradation

“…These findings suggest that inorganic lead halide heterostructure has the potential to be used for heavy metal degradation and water pollution removal catalysts. Lead tri-halide perovskites have been considered as a fascinating class of materials for next generation applications due to their remarkable characteristics, including enhanced optical features, high extinction constant, tunable bandgap, versatile surface chemistry, long-range electron-hole diffusion, and high carrier mobility (Akkerman et al, 2015;Gull et al, 2020). This class of materials possesses the general formula of ABX 3 where A is a cation (organic/inorganic), B is a divalent metal (Pb 2+ , Sn 2+ , Ge 2+ ), and X is an anion (Cl 1-, Br 1-, I 1or mixture) (Kulkarni et al, 2019;Yang et al, 2019).…”
