Luminescent materials, Ca2Al2SiO7:Ce3+, Dy3+and CaAl2O4:Mn4+were synthesised by solid phase reaction. The red luminescence of CaAl2O4: Mn4+shows an asymmetric broadband peak at 650 nm corresponding to the characteristic luminescence of Mn4+ions. The luminescent spectra of Ca2Al2SiO7:Ce3+, Dy3+phosphors consist of a broadband peak at 420 nm corresponding to the luminescence of Ce3+ions and narrow lines of Dy3+ions. When mixing Ca2Al2SiO7:Ce3+, Dy3+and CaAl2O4: Mn4+materials, the luminescence spectrum was consistent with the absorption maximum of chlorophyll aand chlorophyll b. Therefore, the material could be used in lighting technology for agriculture, tissue culture and transplanting. Moreover, Nano silver solution is synthesized from Paederia foetida L. leaf extract and silver nitrate solution. Nano silver solutions can be used to kill fungus as well as bacteria and to increase the light absorbance of chlorophyl.
