The monolayers were self-assembled in a stacked configuration at the water\/air interface using Langmuir\u2013Blodgett (LB) techniques. Under continuous 532 nm laser illumination on the red absorption edge of the blue-emitting smaller QDs (QD450), the red-emitting larger QDs (QD645) exhibited oscillatory temporal dynamics in their photoluminescence (PL), characterized by a pronounced blueshift in the emission peak wavelength and an abrupt decrease in peak intensity. Conversely, excitation by a 405 nm laser on the blue absorption edge induced a drastic redshift in the emission wavelength over time. These significant shifts in emission spectra are attributed to photon- and anisotropic-strain-assisted interlayer atom transfer. The findings provide new insights into strain-driven atomic rearrangements and their impact on the photophysical behavior of QD systems.<\/jats:p>","DOI":"10.3390\/nano15141113","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T10:10:38Z","timestamp":1752833438000},"page":"1113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Light-Driven Quantum Dot Dialogues: Oscillatory Photoluminescence in Langmuir\u2013Blodgett Films"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0431-8705","authenticated-orcid":false,"given":"Tefera Entele","family":"Tesema","sequence":"first","affiliation":[{"name":"Department of Chemistry, Prairie View A&M University, Prairie View, TX 77446, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"354","DOI":"10.1038\/370354a0","article-title":"Light-emitting diodes made from cadmium selenide nanocrystals and a semiconducting polymer","volume":"370","author":"Alivisatos","year":"1994","journal-title":"Nature"},{"key":"ref_2","first-page":"2101180","article-title":"Color conversion materials for QD-based displays: Current status and perspectives","volume":"10","author":"Lee","year":"2022","journal-title":"Adv.
