Abstract
The optical properties and quantum efficiency of potential red 
phosphors for a novel phosphor liquid crystal display (LCD) are measured under near‐UV excitation (394 nm). The quantum efficiency of 
phosphor fired at 900°C for 3 h is 0.46 at 365 nm and 0.54 at 394 nm. The optical and morphological suitability of 
phosphors is discussed for their application in phosphor LCDs. The emission peak of 
phosphor is located at 615 nm and the Commission International del'Eclairage (CIE) coordinates are x = 0.63, y = 0.33. © 2000 The Electrochemical Society. All rights reserved.
