However, the device performance of SnO₂-based QLEDs is still significantly lower to those of ZnO-based devices, suggesting considerable room for improvement. Here, we demonstrate the use of Ga-doped SnO₂ nanoparticles with tunable mobility and conductivity for constructing high-performance SnO₂-based QLEDs. The influences of Ga-doping concentration on the mobility and conductivity of SnO₂ nanoparticles are systematically investigated. The mobility and conductivity of Ga-doped SnO₂ nanocrystals can be tuned over two orders of magnitude by varying Ga-doping level. This p-type doping strategy effectively suppresses excessive electron transport in the SnO₂ nanocrystals, thereby promoting more balanced charge injection within the QLED structure. As a result, red-emitting inverted QLEDs incorporating 3.5 at% Ga-doped SnO₂ nanocrystals achieve an average external quantum efficiency (EQE) of 17.36% and a peak EQE of 20.04%. These results suggest that Ga-doped SnO₂ nanocrystals are excellent candidates for the fabrication of high-performance QLEDs.</p>\u0000 </div>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 11","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147569256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains challenging to achieve efficient deep-blue HLCT emitters, since strong charge transfer (CT) character leads to red shifted emission. Herein we demonstrated that the intensity of CT state can be modulated through strategic incorporation of phenyl rings to regulate the spatial separation between building blocks. Detailed investigations revealed that the new emitter CPChN, which exhibits a moderately enhanced charge transfer contribution, undergoes an efficient high-lying reverse intersystem crossing process.

Here, we present a photonic neural network (PNN) based on programmable phase-change metasurfaces, which realizes an on-chip reconfigurable parallel computing architecture through the monolithic integration of non-volatile programmable power beam-splitters, higher-order mode couplers, and multimode cross-waveguides. The programmable power beam-splitter achieves a high precision of 9 bits, supports TE₀ and TE₁ input modes, and operates across a broad wavelength range of 1480–1620 nm. With matching bandwidths, the mode coupler and cross-waveguide ensure scalability for large-scale optical networks. Fabricated on a silicon-on-insulator (SOI) platform and fully compatible with complementary metal-oxide-semiconductor (CMOS) processes, the PNN demonstrates industrialization potential. In handwritten digit recognition tasks, it achieves a classification accuracy of 98.95%, while exhibiting intrinsic advantages in speed and power efficiency.
