This technique excludes the use of toxic or expensive materials, increasing the availability of two-dimentional binary chalcogenide semicondutors. The structure of the nanocrystals has been studied and the possible formation mechanism of the nanoplates has been proposed. The optical absorption showed that the nanoplates demonstrated wide and tuneable absorption band in the visible and near infrared region. These nanoplates could be interesting for converting solar energy and for nanophotonic devices operating in the near infrared %G English %2 https://univ-rennes.hal.science/hal-01296811/document %2 https://univ-rennes.hal.science/hal-01296811/file/Facile%20synthesis%20of%20CuSe%20nanoparticles.pdf %L hal-01296811 %U https://univ-rennes.hal.science/hal-01296811 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_VC %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ IVER %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CNANO-R %~ UR1-MMS %~ TEST2-HALCNRS
