"indium phosphide magic-sized clusters are so small even single atomic surface defect causes almost total light loss, overcome using precision atomic etching strategy utilizing incremental chemical reactions removing only specific defects leaving core structure intact (previously etching often caused damaged)... fluorine reacts with zinc forming protective layer (passivation) sealing surface... 18.1 (was <1) % luminescence efficiency... also: quantum communication, IR sensing for advanced electronics"
