Study on the energy transfer efficiency from SrAl 2 O 4 :Eu 2+ , Dy 3+ to light conversion agent of red-emitting phosphor: SrAl 2 O 4 :Eu 2+ , Dy 3+ /light conversion agent

Efficient Persistent Luminescence Tuning Using a Cyclodextrin Inclusion Complex as Efficient Light Conversion Materials

“…1618 The higher the content of light conversion agent coating, the less light energy can be absorbed by the SAOED core. 59 Therefore, the initial afterglow brightness of the SAOED/light conversion composite material decreased gradually with the increase of the content of the light conversion layer. As shown in Figure 8c, by means of casting the SAOED/light conversion composite material samples onto the flexible silicone substrates, we fabricated colorful design patterns.…”

“…Consequently, the photons emitted by SAOED were significantly reduced The higher the content of light conversion agent coating, the less light energy can be absorbed by the SAOED core . Therefore, the initial afterglow brightness of the SAOED/light conversion composite material decreased gradually with the increase of the content of the light conversion layer.…”

Dynamic Phosphorescent Color of the Warm-Toned Long-Lasting Phosphor Composite PMMA/RECC@SAOED

“…7,8 The light energy conversion theory and principle of luminescence color overlay make enable producing warm-toned emitting phosphor with strong luminescence intensity and long lifetime. [9][10][11][12][13] Herein, we describe a multicolored, warm-toned long-lasting phosphor composite PMMA/RECC@SAOED, which was prepared by coating coumarin type red-emitting color converter (RECC) on the surface of SrAl 2 O 4 :Eu 2+ , Dy 3+ (SAOED) with the help of the encapsulation of polymethyl methacrylate (PMMA). By taking advantage of the long-persistence luminescence of SAOED to stimulate RECC, red fluorescence can be released by RECC.…”
