Quantum efficiency of yttrium and terbium garnets

A measurement system and mathematical procedure are developed for determining the quantum efficiency of luminescent materials. This technique based on standard photoluminescence DARSA PSI 5100 system (Diode Array Rapid Scan Analysis, Professional Scientific Instrument Co, Korea) or any other t...
