The development of a novel composite phosphor converter based on single-crystalline films of Tb₃Al₅O₁₂:Ce garnet and Y₃Al₅O₁₂:Ce single-crystal substrate is reported. The liquid phase epitaxy growth method is chosen for the fabrication of the Tb₃Al₅O₁₂:Ce/Y₃Al₅O₁₂:Ce epitaxial structures with excellent photoconversion properties for application in white light-emitting diodes (LEDs). The influence of Ce³⁺ concentration and thickness of Y₃Al₅O₁₂:Ce substrate as well as the thickness of Tb₃Al₅O₁₂:Ce films on the photoconversion properties is investigated for the construction of warm white LEDs prototypes based on the developed composite phosphor converters.
