Synthesis and low-order optical nonlinearities of colloidal HgSe quantum dots in the visible and near infrared ranges
We synthesize colloidal HgSe quantum dots and characterize their nonlinear refraction and nonlinear absorption using a Nd:YAG laser and its second harmonic. The 7.5 nm quantum dots were synthesized using the hot-injection method. The nonlinear absorption (β = 9×10ˉ⁷ cm Wˉ¹) and negative nonlinear re...
