Low-temperature solution-phase synthesis of quantum well structured CdSe nanoribbons.

Quantum well structured CdSe nanoribbons with uniform and ultrathin thickness of 1.4 nm were synthesized from the low-temperature reaction of CdCl2 and ammonium selenocarbamate. The CdSe nanoribbons exhibited an extremely narrow photoluminescence band with fwhm of 70 meV.
