Summary
This study introduces a novel zero-dimensional organic-inorganic metal halide for single-component white light emission. Doping with antimony fine-tunes the luminescence, enabling efficient solid-state lighting applications.
Area of Science:
- Materials Science
- Solid-State Chemistry
- Luminescence
Background:
- Low-dimensional organic-inorganic metal halides (OIMHs) are promising for solid-state lighting due to their single-component white light emission.
- Developing new OIMHs with tunable luminescence properties is crucial for advancing lighting technology.
Purpose of the Study:
- To synthesize and characterize a new zero-dimensional (0D) indium-based OIMH, (TMPDA)[InCl5(H2O)].
- To investigate its luminescence properties and explore the effect of antimony (Sb) doping on emission characteristics.
- To achieve single-component white light emission from this novel material.
Main Methods:
- Crystallization and structural analysis of the 0D OIMH.
- Photoluminescence spectroscopy to analyze emission spectra and mechanisms.
- Theoretical calculations to understand electronic structures and emission origins.
- Antimony doping to tune luminescence and achieve white light emission.
Main Results:
- The synthesized (TMPDA)[InCl5(H2O)] exhibits dual-band emission originating from organic ligands and self-trapped excitons.
- Antimony doping introduces an additional orange emission band.
- By adjusting Sb doping levels, emission color can be tuned, and single-component white light emission is achieved.
Conclusions:
- A new 0D In-based OIMH with hydrogen bonds shows potential for solid-state luminescence.
- Antimony doping offers a viable strategy to tune the emission color and achieve white light.
- This material demonstrates promise for next-generation single-component white light emitters.

02:39Emission Spectra
51.0K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

01:23IR Spectrum Peak Broadening: Hydrogen Bonding
853
The vibrational frequency of a bond is directly proportional to its bond strength. As a result, stronger bonds vibrate at higher frequencies, while weaker bonds vibrate at lower frequencies. The stretching vibration of the strong O–H bond in alcohols and phenols (very dilute solution or gas phase) appears as a sharp peak at 3600–3650 cm−1.
However, the extent of hydrogen bonding influences the observed stretching frequency and band broadening. Intermolecular or intramolecular...

01:21IR Absorption Frequency: Hybridization
639
Hydrocarbons such as alkanes, alkenes, and alkynes show characteristic C–H stretching absorption bands. These IR stretching frequencies depend on the hybridization of the involved carbon atom and can be explained in terms of the s character of each hybridized atomic orbital.
Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that...

01:27Inductive Effects on Chemical Shift: Overview
1.1K
The protons in unsubstituted alkanes are strongly shielded with chemical shifts below 1.8 ppm. Methine, methylene, and methyl protons appear at approximately 1.7, 1.2 and 0.7 ppm, while the proton signal from methane appears at 0.23 ppm. An electronegative substituent, such as chlorine, withdraws the electron density from the protons, increasing their chemical shift. Progressive substitution of the hydrogens in methane by chlorine shifts the proton signals increasingly downfield, to 3.05 ppm in...
