Abstract
In response to the growing demand for photoluminescent (PL) systems with versatile emission color tuning capabilities, particularly in the realm of contemporary versatile optoelectronic devices, we have developed a straightforward and environmentally friendly PL system. This system is designed to effectively tune its photoluminescence color response to various stimuli, including the system’s composition and excitation wavelength. Notably, our PL system achieves an almost pure white light emission (WLE), which has significant value in diverse applications. To create this interesting system, we combine two nano-Group of Uniform Materials Based on Organic Salts (nano-GUMBOS), namely nPBIL and nRBS, within an aqueous mixture. By precisely adjusting the composition of these nano-GUMBOS, we successfully achieved a near-pure WLE with a Commission Internationale d’Eclairage (CIE) 1931 color profile of (0.31, 0.31) when excited at a wavelength of 365 nm. This achievement demonstrates the system’s capability to produce high-quality WLE, meeting the requirements for efficient and aesthetically pleasing illumination which is significant to various optoelectronic applications. The straightforward synthesis process and environmentally friendly nature of our PL system make it an attractive choice for various lighting and display applications. The adaptability and tunability of the emission color add further versatility to its potential uses, providing opportunities for state-of-the-art solutions in the field of optoelectronic technology.
期刊介绍:
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
