Photoluminescence of cerium-doped (Ca1−xSrx)3RE2Ge3O12 garnet phosphors for solid state lighting: Relating structure to emission

- A novel family of green-emitting cerium-doped garnet phosphors was synthesised.
- Links between structural properties and photoluminescence were investigated.
- Emission shifts were related to doping-site distortion and electronegativity.
- Red- and blue-shifts were achieved by changing the cations in the garnet host.
