Synthesis and Optical Properties of Linker-Free TiO<sub>2</sub>/CdSe Nanorods
Bibliographic record
Abstract
Linker-free TiO 2 /CdSe hybrid nanorods (NRs) were prepared by growing CdSe QDs in the presence of TiO 2 NR seeds using seeded–growth type colloidal injection approach. TEM studies revealed the abundant formation of anatase TiO 2 NRs with different lengths. We found that the as-prepared TiO 2 seeds determined the morphology of TiO 2 /CdSe NRs. The photophysics of these materials were studied by photoluminescence (PL) and femtosecond transient absorption spectroscopy. While we observed the efficient PL quenching in TiO 2 /CdSe NRs, the bleach dynamics of TiO 2 /CdSe NRs is similar to that of CdSe NRs. It suggests that while surface traps that arise from the lattice mismatch between CdSe and TiO 2 are mainly observed in transient absorption measurements the ultrafast exciton dissociation over the experimental time resolution occurs in TiO 2 /CdSe NRs.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
