Special Issue Information

Dear Colleagues,

Photochemistry is a branch of chemistry with strong connections to a wide range of scientific fields, including physics, organic and inorganic chemistry, material science, biology and medicine. Key areas of photochemical research include the study of photon absorption, energy transfer, electron transfer and the dynamics of excited states. Advanced photocatalysts are a major focus in photochemistry due to their potential applications in solar energy conversion, environmental remediation and synthetic chemistry.

Interdisciplinary collaboration, combining our knowledge from chemistry, physics and material science, is crucial for addressing complex photochemical challenges. Recent advances in spectroscopic techniques and computational modelling are providing deeper insights into the fundamental aspects of photochemistry.

Photochemistry in Asia has been an active field for decades. Therefore, it is our pleasure to announce a new Special Issue entitled as such, i.e., “Photochemistry in Asia”. This Special Issue will present a high-quality collection comprising works from scientists in Asian countries, with both original research articles and comprehensive review papers being welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Ternary In1−xGaxP quantum dots (QDs) have emerged as promising materials for efficient blue emission, owing to their tunable bandgap, high stability, and superior optoelectronic properties. However, most reported methods for Ga incorporation into the InP structure have predominantly relied on cation exchange in pre-grown InP QDs at elevated temperatures above 280 °C. This is largely due to the fact that, when heating In and P precursors in the presence of Ga, an InP/GaP core–shell structure readily forms. Herein, we introduce a novel synthesis approach using the indium precursor [In(btsa)2Cl]2 and GaI3 to fabricate In1−xGaxP QDs in a single step at relatively low temperatures (200 °C). By adjusting the GaI3 content, we achieved controlled emission tuning from red to blue. Structural and compositional analysis through X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) confirmed successful Ga3+ incorporation into the QD core, with a corresponding blue shift in the emission as GaI3 content increased. The synthesized QDs demonstrated a photoluminescence quantum yield (PLQY) of ~50% and a full width at half maximum (FWHM) of 45~62 nm, highlighting the potential of this synthesis method for advanced optoelectronic applications.
