Two novel lead-free tin-based 0D halides were synthesized as stable alternatives to perovskites. These materials exhibit broadband yellow and yellow-green light emissions, showing promise for solid-state lighting applications.
Area of Science:
- Materials Science
- Inorganic Chemistry
- Solid-State Lighting
Background:
- 3D lead-based perovskite nanocrystals face challenges due to instability and toxicity.
- Lead-free low-dimensional organic-inorganic hybrid metal halides are emerging as promising alternatives.
Purpose of the Study:
- Synthesize new tin-based 0D halides as potential substitutes for perovskites.
- Investigate their photoluminescence properties and stability for lighting applications.
Main Methods:
- Synthesis of two new tin-based 0D halides: [H4BAPP]SnBr5·Br and [H4BAPP]SnCl5·Cl·H2O.
- Characterization of their crystal structures and photoluminescence properties.
- Evaluation of their chemical and thermal stability.
Main Results:
- Successful synthesis of [H4BAPP]SnBr5·Br and [H4BAPP]SnCl5·Cl·H2O using [SnX5]3- as the emission center.
- Observation of broadband yellow and yellow-green emissions attributed to self-trapped excitons (STEs).
- Photoluminescence quantum yields (PLQYs) of 19.27% and 2.36% were recorded for the two compounds, respectively.
Conclusions:
- The synthesized tin-based 0D halides demonstrate excellent chemical and thermal stability.
- Their broadband emission characteristics suggest potential applications in solid-state white lighting diodes.

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

02:45Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
