Abstract
We reported the fabrication of 1D photonic crystal structure and investigated its application for tuning colloidal CdSe quantum dot emission. The photonic crystals was made by using sol-gel method and consists of TiO2 and SiO2 multilayers on glass substrate. The colloidal quantum dot is CdSe quantum dot with emission wavelength around 630 nm, which is similar to photonic band gap of fabricated photonic crystals. The quantum dot was dropped and dried on the opposite side of photonic crystals. We measured angle dependence of transmission of photonic crystal and angle dependence photoluminescence of quantum dot emission. We found that quantum dot emission was influenced by excitation angle ; therefore photonic crystals can be useful for tuning the emission of quantum dot. We have confirmed that the angle dependence photoluminescence of quantum dot is significantly related to photonic band gap of photonic crystal. This work leads to future application of photonic crystal on quantum dot emission such as quantum dot lasing.
