  Two classes of important nano-materials, mesoporous titania (MT) and CdSe quantum dots, are prepared via chemical methods. Rapid immobilization of CdSe quantum dots into mesoporous titania has been achieved and the composite system is characterized by high-resolution transmission electron microscopy and photoluminescence. The band-to-band photoluminescence emission of CdSe quantum dots is blue-shifted for 20nm after the dots are immobilized into mesoporous titania. Loading CdSe quantum dots into mesoporous titania leads to speedy photoelectric exchange process of the system and a significant rise in photoconductivity (for a factor of 8), which would attract great deal of attention in quantum dots solar cell.
