主 题:Carbon dots Full-color Fluorescent centers Concentration and excitation White-light LEDs
摘 要:The paper describes a kind of truly full-color photoluminescence(PL)*** CDs were prepared by using one-pot hydrothermally heating citric acid and formamide at 200℃ for 2 *** CDs have three fluorescent centers at blue,green,and red light *** color was regulated through two means,including changing excitation wavelengths or CDs *** emission maxima changed from blue to red with the increase of excitation wavelengths or CDs *** full-color PL behavior of the CDs was inherited and conserved in the solid polymer matrix,giving multicolor CDs/polymer films and light emitting diodes(LEDs).White-light LED(WLED)with the CIE coordinate approaching to(0.31,0.32)were also achieved.
