Photoluminescence: Applications

Photoluminescence: Applications

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...

Background:

Traditional room-temperature phosphorescent materials have limited operational temperatures.
Achieving tunable high-temperature afterglow from a single molecule is challenging.

Purpose of the Study:

To develop organic amorphous materials with simultaneous effective phosphorescence and tunable high-temperature afterglow.
To explore a strategy for designing tunable high-temperature afterglow-emitting amorphous polymers.

Main Methods:

Employing host-guest anchoring coupled with single-bond rotors.
Investigating temperature-dependent changes in excited-state conformation.
Characterizing wavelength-tunable afterglow properties (chromaticity, lifetime) from 298 K to 473 K.

Main Results:

Demonstrated effective phosphorescence and tunable afterglow at high temperatures from a single luminescent molecule.
Observed a shift in chromaticity coordinates from (0.24, 0.47) to (0.18, 0.20) and a decrease in lifetime from 836 ms to 6.34 ms upon heating.
Theoretical investigations confirmed temperature-dependent transformation of excited-state conformation as the cause of tunable afterglow.

Conclusions:

A novel strategy using host-guest anchoring and single-bond rotors enables tunable high-temperature afterglow in organic amorphous materials.
The developed materials offer potential for advanced applications requiring stable and tunable phosphorescence at elevated temperatures.
This work advances the design principles for organic phosphorescent materials with controllable high-temperature afterglow emission.
