Red Emitting Phosphors Doped with Mn and Eu Ions for pc-WLEDs

摘要

A new red emitting phosphors based on oxyfluoride glass and glassceramics doped with europium and manganese ions were synthesized and their optical properties and structure were studied. The transparent ceramic matrices for phosphors were selected because they overcome traditional powder phosphors due to high chemical and thermal stability and low temperature sensitivity. The fluoride based red emitting phosphors combined with green one and blue emitting chip used to fabricate phosphor converted white LEDs with warm color temperature and improved color rendering indexes.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35375
