Low-voltage cathodoluminescence properties of green-emitting ZnAl2O4:Mn2+ nanophosphors for field emission display

Fabrication and luminescence properties of one-dimensional ZnAl2O4 and ZnAl2O4: A3+ (A=Cr, Eu, Tb) microfibers by electrospinning method

“…Compared to cathode ray tubes (CRTs) phosphors, FEDs phosphors are required work at lower voltage (1-6 kV) but with higher current density (1 mA/cm 2 ). Thus FEDs Phosphors should not only be efficient at low voltages but also be resistant to coulombic aging and saturation at high current densities [2]. Highly efficient sulfide phosphors widely used in CRTs are not suitable for FEDs, because they emit gases which damage the cathode components and decrease the lifetime of the display.…”

Luminescent properties and X-ray photoelectron spectroscopy study of ZnAl2O4:Ce3+,Tb3+ phosphor

“…Zinc aluminate (ZnAl 2 O 4 ) is a well known semiconductor with a wide bulk band gap of 3.5-3.9 eV [1][2][3][4][5][6]. It belongs to a class of mixed-metal oxides called the spinels which are commonly represented by a general chemical formula AB 2 O 4 where A and B are divalent (2+) and trivalent (3+) cations, respectively.…”

“…Traditionally, ZnAl 2 O 4 with normal, intermediate or inverse spinel structure is widely used as a catalyst or ceramic [9]. Today, it is used in many applications such as optoelectronics, sensor technology and information display technology [1,2,5,6] because of its excellent optical and hydrophobic properties and high chemical and thermal stability [10]. For application in display technologies, ZnAl 2 O 4 is used as host matrix for trivalent rare-earth ions (e.g.…”

Nanophosphor Coatings: Technology and Applications, Opportunities and Challenges

“…In this case, however, the main benefit was the increased phosphor efficiency attributed to the improved crystallinity and surface microstructure, not the decreased scattering. New works on nanophosphors for low-voltage cathodoluminescence have occasionally been published since then (Chang et al, 2010;Shang et al, 2012;Wang et al, 2011).…”
