style="text-indent:25px">影響熒光粉亮度的因素有很多，例如：1、紙張因素。應(yīng)選擇證券紙或無熒光增白劑的紙，這樣的效果較理想。在有熒光增白劑的紙（普通紙）上印刷時(shí)，熒光效果會(huì)明顯減弱。紙張的增白劑含量越多，熒光效果越弱；反之，則較強(qiáng)。故在用普通紙時(shí)，盡可能選用低增白劑的紙張；2、墨層厚度。印品墨層越薄，熒光效果越弱；墨層較厚，熒光效果越強(qiáng)，但同時(shí)印跡也越明顯。用戶在使用無色熒光油墨時(shí)，如能注意這些特點(diǎn)，一定能達(dá)到良好的印刷及防偽效果。</p><p

style="text-indent:25px">白光LED的制作方式主要有兩種，一種是采用紅、綠、藍(lán)三基色LED芯片封裝成白光LED，另一種是利用單個(gè)LED芯片配合熒光粉。后一種方式在生產(chǎn)成本、散熱和控制電路上具有優(yōu)勢(shì)，在工業(yè)上為常用。因而，熒光粉是半導(dǎo)體照明的關(guān)鍵材料之一。目前，LED用的熒光粉主要有三大體系，即鋁酸鹽、硅酸鹽和氮(氧)化物。YAG粉和TAG粉為常用的黃粉，LuAG粉為綠粉，量子效率均大于90%，同時(shí)具有優(yōu)良的化學(xué)穩(wěn)定性和熱穩(wěn)定性。硅酸鹽體系主要有M2SiO4:Eu2+和M3SiO5:Eu2+(M=Ca,Sr,Ba)熒光粉。前者可作為綠粉和黃粉，后者是橙色粉。這類硅酸鹽熒光粉的化學(xué)穩(wěn)定性和熱穩(wěn)定性相對(duì)要差一些。熒光粉的耐光性差，不適合在室外長(zhǎng)期使用。金華好用的熒光粉藍(lán)色</p><p
