Preparation and photoluminescence characteristics of Eu3+-doped MgAl1.8Y0.2O4 nanocrystals

Preparation and luminescence properties of Tb3+ doped ZrO2 and BaZrO3 phosphors

“…The aim is to develop luminescent materials of three basic colours with higher radiative efficiency. In this study combustion synthesis method has been used to synthesize ZrO 2 and BaZrO 3 doped with different concentrations of Tb 3 + ions [14,15]. The synthesized powders are further treated at different temperatures to see its effect on photoluminescence and crystallinity of the materials.…”

Photoluminescence properties of Eu3+:MgAl2O4 powder phosphor

“…However in most hosts, the luminescence of Eu occurs in blue and red regions. Luminescence of Eu 3+ in the case of a non-centro symmetric environment, 5 D 0 → 7 F 2 transition causes a red emitting phosphor suitable for lamps and displays [28], but as far as we know, less attention has been made on the study of luminescence properties of Eu 3+ :MgAl 2 O 4 phosphor prepared by a solid-state reaction method [29]. In the present work, luminescence properties of MgAl 2 O 4 :Eu 3+ phosphor is reported through emission, excitation, lifetime and structural from X-ray diffraction (XRD), FESEM and FT-IR measurements.…”

Preparation of nano phosphors by Microwave-assisted combustion synthesis

“…Most inorganic compounds doped with rare earth ions form an important class of phosphors as they possess a few interesting characteristics such as excellent chemical stability, high luminescence efficiency, and flexible emission colors with different activators [8,9]. Rare earth ions-activated nano structured materials have been attracting much interest in the past few years, due to the excellent luminescence and potential applications in luminescent devices and display equipment, such as lighting, field emission display (FED), cathode ray tubes (CRT), and plasma display panels (PDP) [10][11][12][13][14][15].…”
