초록
HgTe quantum dots were synthesized in aqueous solution at room temperature by colloidal method. The synthesized materials were identified to be zincblende cubic structured HgTe quantum dots by X-ray diffraction and transmission electron microscopy image revealed that these quantum dots are agglomerate of a individual particle. The colloidally prepared HgTe quantum dots have the sphere-like shape with a diameter of approximately 4 nm. The optical properties of the HgTe quantum dots were investigated with photoluminescence(PL). The PL appears in the near-infrared region, which represent a dramatic shift from bulk HgTe behavior. The analytic results revealed that HgTe quantum dots have the broad size distribution, as PL emission spectrum covers the spectral region from 900 to 1400 nm. In this study, the factors affecting PL of HgTe quantum dots and particle size distributiont are described. 會Ā᐀ 䁇?⨀ 젲岒 Ā 㰀 會Ā㰀 顇?⨀ 끩 Ā ㈀ 會Ā㈀ ?⨀ 䡪 ఀ Ā ᐀ 會Ā᐀ 䡈?⨀ Ā ᐀ 會Ā᐀ ꁈ?⨀ 硫 ᜀ Ā 저 會Ā저 ?⨀ 샟ග ऀ Ā 저 會Ā저 偉?⨀ 栰岒 ఀ Ā 저 會Ā저 ꡉ?⨀ 1岒 Ā 저 會Ā저 J?⨀ 惝ග Ā 會Ā 塊?⨀ ග 嘀 Ā 切 會Ā切 끊?⨀ ⣟ග Ā 搀 會Ā搀 ࡋ?⨀ 큭킢 Ā 저 會Ā저 恋?⨀ 桮킢 Ā 저 會Ā저 롋?⨀ ⣅沥 ࠀ Ā ࠀ 會Āࠀ ၌?⨀ 샅沥 Ā 저 會Ā저 桌?⨀ 壆沥 ሀ Ā 저 會Ā저 쁌?⨀ o킢 瀀 ꀏ 會Ā ᡍ?⨀ 棤좗 Ā Ā Ā 會ĀĀ 灍?⨀ å좗 Ā Ā Ā 會ĀĀ 졍?⨀ 飥좗 Ā Ā Ā 會ĀĀ ⁎?⨀ ?ꆟ ᤀ
