Zusammenfassung: | CdTe@Zn5(CO3)2(OH)G composites were synthesized by a hydrothermal method. CdTe@Zn5(CO3)2(OH)6 composite nanospheres were characterized via X-ray diffraction, scanning electron microscopy, energy- dispersive 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. |
