摘要: The presence of a strong, changing, randomly-oriented, local electric field, which is induced by the photo-ionization that occurs universally in colloidal semiconductor quantum dots (QDs), makes it difficult to observe quantum-confined Stark effect ensemble QDs. We propose way inhibit such random and clear shift observed directly close-packed Besides applications optical switches modulators, our experimental results indicate how oscillator strengths transitions are changed under external fields.
