Luminescence properties of CdTe QDs embedded in Zn5(CO3)2(OH)6 matrix

CdTe@Zn₅(CO₃)₂(OH)₆ composites were synthesized by a hydrothermal method. CdTe@Zn₅(CO₃)₂(OH)₆ composite nanospheres were characterized via X-ray diffraction, scanning electron microscopy, energydispersive X-ray spectroscopy, and photoluminescence (PL). The hydrothermal reaction time and the mole ratios of Zn/Te played important roles in the growth and fluorescence intensity of CdTe@Zn₅(CO₃)₂(OH)₆ composites. The composite powders showed peak PL at 578 nm at 1.6 times the intensity of powdered CdTe QDs. CdTe@Zn₅(CO₃)₂(OH)₆ exhibited a strong yellow fluorescence emission, and its preparation method was easy and economical. Therefore, CdTe@Zn₅(CO₃)₂(OH)₆ offers potential applications in biological markers and light-emitting diodes.
