To understand these outstanding properties, a thorough analysis of the band-edge exciton emission is needed which is not reachable in ensemble and room temperature studies because of broadening effects. Here, we report on a cryogenic-temperature study of the photoluminescence of single CsPbBr$_3$ NCs in the intermediate quantum confinement regime. We reveal the size-dependence of the spectral features observed: the bright-triplet exciton energy splittings, the trion and biexciton binding energ","authors_text":"Aur\\'elie Pierret, Caixia Huo, Carole Diederichs, Christophe Voisin, Mohamed-Raouf Amara, Qihua Xiong, WeiBo Gao, Zakaria Said","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2023-01-23T17:29:19Z","title":"Spectral fingerprint of quantum confinement in single CsPbBr$_3$ nanocrystals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2301.09571","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4e53a7f6620b5adf2937575aa41b15504fb816f9139a6f58979cb5d8ab323b1e","target":"record","created_at":"2026-07-05T05:58:40Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"31c0ec7fc376c78516709fa1e9f8ff3802be8c1228335cd9a080db3242f5bd02","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2023-01-23T17:29:19Z","title_canon_sha256":"d4ebb8acfbaddb97989fb0f7aef2dbd2c7c364012e2ad604bd7d970b727d5feb"},"schema_version":"1.0","source":{"id":"2301.09571","kind":"arxiv","version":2}},"canonical_sha256":"f1efe138c83cd1eb1abed33191e5a114eedd34f9a71735e7969db80d404f0447","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f1efe138c83cd1eb1abed33191e5a114eedd34f9a71735e7969db80d404f0447","first_computed_at":"2026-07-05T05:58:40.529407Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:58:40.529407Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pMo5RaJjWEX2DNDBWww3IH+zj8shb4pv/iwe3N3b/MNlH/eC1d081yDlTTXVTAm8j4QBNn8D3OqzMMIdT5J3Ag==","signature_status":"signed_v1","signed_at":"2026-07-05T05:58:40.529859Z","signed_message":"canonical_sha256_bytes"},"source_id":"2301.09571","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4e53a7f6620b5adf2937575aa41b15504fb816f9139a6f58979cb5d8ab323b1e","sha256:5abe6d5e28b832a893f8613ca30939b6c2028e869b1ae5c2df3af552d6b88e1d"],"state_sha256":"89252da35196da952721c150e9d36cf2fffe982870aea8ee17f75d7399ca58ce"}
