Photoluminescence: Applications

859
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Photoluminescence: Fluorescence and Phosphorescence

3.1K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Color in Coordination Complexes
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...

Variables Affecting Phosphorescence and Fluorescence

1.1K
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Area of Science:

  • Materials Science
  • Photochemistry
  • Coordination Chemistry

Background:

  • Tunable long persistent luminescence (LPL) materials are crucial for security, anti-counterfeiting, and data encryption.
  • Existing tunable LPL materials are predominantly organic molecules or polymers, limiting their structural diversity and properties.

Purpose of the Study:

  • To synthesize novel metal-organic coordination polymers with color-tunable LPL properties.
  • To investigate multi-mode dynamic color tuning capabilities in single-component coordination polymers.

Main Methods:

  • Self-assembly of HTzPTpy ligand with different cadmium halides (CdCl2, CdBr2, CdI2).
  • Solid-state characterization of LPL emission colors under varying time, excitation, and temperature.
  • Single-crystal X-ray diffraction analysis and theoretical calculations to elucidate luminescence mechanisms.

Main Results:

  • A series of metal-organic coordination polymers exhibiting color-tunable LPL were successfully synthesized.
  • Multi-mode dynamic color tuning from green to yellow or green to red was achieved by time-evolution, excitation, and temperature.
  • The tunable LPL is attributed to the balanced interplay of single molecule and aggregate triplet excited states, influenced by heavy-atom effects from halide anions.

Conclusions:

  • This study presents the first single-component coordination polymer materials with multi-mode dynamic color-tunable LPL.
  • Rational incorporation of halide anions into coordination polymers is an effective strategy for achieving multi-color LPL.
  • These findings open new avenues for advanced optical materials in security and data storage applications.
