In this work, Ge QDs, pumped by an above bandgap near–infrared wavelength, exhibit THz amplitude modulation in the frequency range of 0.1–1.0 THz. The epitaxial Ge QDs outperform the reference SOI (170 nm top Si) substrate in THz amplitude modulation due to higher carrier generation in weakly confined dots compared to their bulk counterpart. This is further corroborated using a theoretical model based on the nonequilibrium Green’s function (NEGF) method. This model enables the calculation of photocarrier generated (PCG) and their confinement in the Ge QD region. Our model also reroutes the calculation from PCG to the corresponding plasma frequency and hence to refractive index and THz photoconductivity. Moreover, the photogenerated confined holes’ accumulation at the Ge QDs/Si interface is elevated after optical illumination, leading to decreased THz photoconductivity. This augmentation in THz photoconductivity contributes to a significant enhancement of THz modulation depth of ∼77% at Ge QDs/Si interfaces compared to bare SOI at 0.1 THz.</p>","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"2 10","pages":"2085–2091 2085–2091"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142516877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, bulky and expensive commercial fluorescence microscopes are usually required. The Stokes shift property of most commonly used fluorophores requires optical sets such as dichroic mirrors and specific filters in the optical pathway before a photodetector to eliminate excitation and scattering lights from the fluorescence signals. The fluorescence signal collected by an objective is further unavoidably attenuated, and the optical resolution is diffraction-limited. Herein, a proof of concept of a lab-on-a-chip compatible molecular sensor is shown by integrating upconversion nanoparticles (UCNPs) and amorphous hydrogen-doped InGaZnO (InGaZnO:H) thin-film phototransistor (IGZO:H TFTs) aiming to alleviate those issues. Upon illumination with a 980 nm infrared light, the phototransistor shows no photocurrent without UCNPs but yields a high photocurrent with UV–visible fluorescent light emitted from the UCNPs. The molecular detection is enabled by further involving the Förster resonance energy transfer (FRET) mechanism, with the UCNPs as donors. The photocurrent falls back to its original low level when biotinylated gold nanoparticles are added to selectively bind and quench the UCNPs via biotin–streptavidin coupling. Each UCNP shows an estimated photocurrent-to-dark current ratio of 10<sup>3</sup> and each biotinylated gold nanoparticle causes at least 1 order of magnitude decrease of the photocurrent.

NIR-to-visible photon upconversion has been previously demonstrated in PbS/CdS/CdSe core/multishell heterostructures, but their reported upconversion efficiencies are low. The upconversion performance could be significantly improved by engineering the PbS/CdS core/shell intermediate structure to achieve the quasi-type II band structure and carrier separation behavior known to promote the upconversion process. Here we address two critical challenges to realizing an optimized PbS/CdS intermediate structure that could enable efficient upconversion in full PbS/CdS/CdSe structures. We first use computational simulations to predict the band alignment and carrier behavior in PbS/CdS and PbS/CdS/CdSe as a function of PbS core size and CdS shell thickness. We use the results to develop synthesis targets for PbS/CdS predicted to achieve effective carrier separation and improved upconversion performance. Next, we synthesize a library of PbS/CdS quantum dots via cation exchange across three particle sizes. We analyze the reaction products using absorbance, PL, and transmission electron microscopy to create a framework for the predictive synthesis of PbS/CdS with the target core and shell dimensions. Finally, we combine our computational and experimental findings to identify and understand a trade-off in design and synthetic factors required to realize PbS/CdS structures that provide a foundation for efficient NIR-to-visible upconversion.</p>","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"2 10","pages":"2184–2195 2184–2195"},"PeriodicalIF":0.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
