摘要
Abstract
In this study,Eu3+replaced Gd3+in a series of Ca2Gd(1-x)Ga3Ge2O12:xEu3+(CGGG:Eu3+)garnet-based phosphors.The crystal structure of the samples were investigated by X-ray powder diffraction.The luminescence properties of the samples were studied using fluorescence excitation spectroscopy,emission spectra,temperature-dependent emission spectra and fluorescence quantum yield tests.The results show that under UV excitation at 394 nm,the emission light contains the characteristic spectrum of Eu3+ranging from orange to red and to deep red,originating from the 5 D0-7 FJ(J=1,2,3,4)electron transitions.The combination of these three types of light ensures that the wavelength range required for optimal plant growth.The temperature-dependent emission spectra of the samples shows great thermal stability at high temperatures,and the thermal activation energy was calculated to be 0.229 eV.Meanwhile,the quantum efficiency of the representative sample was 85.8%,which means that the luminescent material can efficiently transfer UV light into the light that is mainly absorbed by plants,significantly improving the efficiency of energy use.This discovery opens up new material options in the field of plant growth lighting and provides a basis for further research into the response of plants to different spectra.Future research could explore how these phosphors can be used to provide tailored lighting solutions at different stages of plant growth,thereby improving the efficiency of light energy use and facilitating plant growth.关键词
