中文摘要	we report the growth of hexagonal zno nanorods and nanoflowers on gan-based led epiwafer using a solution deposition method. we also discuss the mechanisms of epitaxial nucleation and of the growth of zno nanorods and nanoflowers. a gan-based led epiwafer was first deposited on a sapphire substrate by mocvd with no electrode being fabricated on it. vertically aligned zno nanorods with an average height of similar to 2.4 mu m were then grown on the led epiwafer, and nanoflowers were synthesized on the nanorods. the growth orientation of the nanorods was perpendicular to the surface, and the synthesized nanoflowers were composed of nanorods. the micro-raman spectra of the zno nanorods and nanoflowers are similar and both exhibit the e-2 (high) mode and the second-order multiple-phonon mode. the photoluminescence spectrum of zno nanostructures exhibits ultraviolet emission centred at about 380 nm and a broad and enhanced green emission centred at about 526 nm. the green emission of the zno nanostructures combined with the emission of ingan quantum wells provides a valuable method to improve the colour rendering index (cri) of leds.
