1.Preparation of Green-Emitting Phosphor (La,Ce,Tb)(PO_4,BO_3) and Investigation of Its Luminescent
3.VARIATION OF LUMINESCENCE PROPERTIES OF A BLUE-GREEN-EMITTING PHOSPHOR (STRONTIUM-BORATE-PHOSPHATE:Eu~(2+)) WITH INGREDIENTS AND TEMPERATURE
4.SrZnO_2 luminescent material is a promising green-emitting phosphor by long wavelength UV excitation because of its luminescence properties.
5.Green-emitting phosphors of lanthanum borophosphate doped with Ce3＋ ,Tb3＋ and Gd3＋ have been prepared using BPO4 and rare earth oxides. The spectroscopic properties of Ce3＋ ,Tb3＋ and Gd3＋ and interaction among them in lanthanum borophosphate have been studied.
6.The doped Alqlayer acts as a red and green-emitting as well as chromaticity-tuning layer,whose thickness and position as well as the concentration of DCJTB in Alqpermit the tuning of the device spectrum to achieve a balanced white emissionwith Commission Internationale De L′Eclairage coordinates of (0.33, 0.33).
7.Green-emitting phosphor coactivated with Ce and Tb has been prepared,which belongs to borophosphate,first by using BPO 4 and rare earth oxides as the principal raw materials. Investigation of energy transfer between Ce 3+ and Tb 3+ shows that the mechanism of energy transfer from Ce 3+ to Tb 3+ is of resonance nature caused by electrical mutipolar interaction,and efficiency of such energy transfer may attain a high of 90%.
9.As a wide-band semiconductor,ZnO can be used for blue-green,blue and ultraviolet light-emitting devices,owing to its large exciton binding energy and large band width which equals to the wavelength of UV light.
10.180 Hi-Line Brown hens were exposed to red (660 nm, R), green (560 nm, G) and blue (480 nm, B) light from light emitting diode (LED) lamps and incandescent light (400~700 nm, W) for19 to 52 weeks and to study the monochromatic light effect on the egg size, eggshell index, long and short length of egg and eggshell quality in this experiment.
