style="text-indent:25px">采用熒光粉來制作彩色LED有以下優(yōu)點：首先，雖然不使用熒光粉，就能制備出紅、黃、綠、藍(lán)，上海熒光粉的視頻、紫等不同顏色的彩色LED，但由于這些不同顏色LED的發(fā)光效率相差很大，采用熒光粉以后，可以利用某些波段LED發(fā)光效率高的優(yōu)點來制備其他波段的LED，以提高該波段的發(fā)光效率。例如有些綠色波的LED效率較低，利用熒光粉制備出一種效率較高，被其稱為"蘋果綠"的LED用于手機背光源，取得了較好的經(jīng)濟效益。其次，LED的發(fā)光波長還很難精確控制，因而會造成有些波長的LED得不到應(yīng)用而出現(xiàn)浪費，例如需要制備470nm的LED時，可能制備出來的是從455nm到480nm范圍很寬的LED，發(fā)光波長在兩端的LED只能以較低廉的價格處理掉或者廢棄，而采用熒光粉可以將這些所謂的"廢品"轉(zhuǎn)化成我們所需要的顏色而得到利用。第三，采用熒光粉以后，有些LED的光色會變得更加柔和或鮮艷，上海熒光粉的視頻，上海熒光粉的視頻，以適應(yīng)不同的應(yīng)用需要。當(dāng)然，熒光粉在LED上比較普遍的應(yīng)用還是在白光領(lǐng)域，但由于其特殊的優(yōu)點，在彩色LED中也能得到一定的應(yīng)用，但熒光粉在彩色LED上的應(yīng)用還剛剛起步，需要進一步進行深入的研究和開發(fā)。熒光粉的價格因質(zhì)量不同、種類不同而不同。上海熒光粉的視頻</p><div

style="text-indent:25px">熒光粉的注意事項：　一、在使用無色熒光油墨前，必須徹底洗凈墨輥、墨槽、印版等相關(guān)部件，以免混入其他顏色。有條件的印刷廠建議留出**設(shè)備、換上新墨輥。二、無色熒光油墨和普通有色墨的顏色搭配。無色紅印油墨；熒光效果好。無色紅印藍(lán)墨或無色藍(lán)印紅墨熒效果較差。底色的深淺不同，對熒光亮度有較大影響，油墨底色越深熒光效果越差。三、紙張印刷時，無色熒光油墨一般做后色印，否則會被其他油墨遮蓋，影響發(fā)光效果。透明塑料印刷時，情況有所不同。外印時熒光油墨做后色。金華質(zhì)量的熒光粉普通熒光燈用熒光粉主要是銻錳的鹵磷酸鈣熒光粉。</p><div

style="text-indent:25px">鹵磷酸鈣熒光粉的發(fā)光是由***劑銻(Sb)和錳Mn共同***的。***劑原子在點陣內(nèi)占據(jù)鈣原子的位置。這種材料具有敏化現(xiàn)象：當(dāng)***劑Sb吸收激發(fā)能后,將一部分能量以光輻射的形式放出，另一部分則在所謂共振傳遞的過程中轉(zhuǎn)移給Mn，使Mn產(chǎn)生本身的輻射。因此，總的輻射取決于兩種***劑的特性，并且隨著它的比例的變化而變化,還取決于氟、氯的比例。如在Sb***的鹵磷酸鈣內(nèi)增加錳的含量，就會增加橙黃色的輻射，而相應(yīng)的減少了藍(lán)色輻射。利用上述現(xiàn)象,只要改變Mn的含量，就可以得到不同色溫的鹵磷酸鈣熒光粉。</p><p style="text-indent:25px">熒光粉材料不是一個一次性使用。是一種具有特殊晶體內(nèi)部結(jié)構(gòu)進行發(fā)光物質(zhì)，它具有極強的吸光－蓄光－發(fā)光技術(shù)能力，當(dāng)受到自然環(huán)境光和燈光的照射時，即吸收并貯存以及部分光能量，并在黑暗中再以可見光的形式緩緩釋放。發(fā)光材料需要經(jīng)過不同光照5分鐘后，在黑暗中可自動發(fā)光12小時以上。吸光和發(fā)光的過程可以有無數(shù)次重復(fù)，發(fā)光壽命達(dá)20年以上。熒光粉的主要特性是什么？一：能自動吸收的任何光源，并且在自動暗處發(fā)光; 二：黃綠熒光粉亮度高，余輝時間長（在日光或燈光照射下進行吸光5-20分鐘，有效持續(xù)不斷發(fā)光可以達(dá)到6-15小時）；三：其耐光、耐老化和化學(xué)穩(wěn)定性，使用壽命15年以上；四：無毒、無放射性、無危險，是新一代綠色發(fā)光材料。光致儲能夜光粉是熒光粉在受到自然光、日光燈光、紫外光等照射后，把光能儲存起來。</p><div

style="text-indent:25px">熒光粉是神奇的，其具備發(fā)光的能力。不過部分發(fā)光粉必須是陽光照射或光照后才能發(fā)光，并有一定的時間。熒光粉涂在產(chǎn)品上，在晚上或黑暗中可以看得見，因為熒光粉有發(fā)光發(fā)亮的功能。在視覺上，相當(dāng)好看。過去，發(fā)光粉末是基于硫化鋅粉末，它本身不發(fā)光，但具有磷光特性，即受到陽光或光的激發(fā)，并在一定時間內(nèi)繼續(xù)發(fā)光，但時間很短。為了使硫化鋅持續(xù)激發(fā)，必須混合一定量的放射性元素。它們以前是放射性鐳，但現(xiàn)在主要是溴。根據(jù)放射性元素的劑量不同，發(fā)光強度也不同。熒光粉的耐光性差，不適合在室外長期使用。金華質(zhì)量的熒光粉</p><p

style="text-indent:25px">采用熒光粉來制作彩色LED有以下優(yōu)點：雖然不使用熒光粉，就能制備出紅、黃、綠、藍(lán)、紫等不同顏色的彩色LED，但由于這些不同顏色LED的發(fā)光效率相差很大，采用熒光粉以后，可以利用某些波段LED發(fā)光效率高的優(yōu)點來制備其他波段的LED，以提高該波段的發(fā)光效率。例如有些綠色波的LED效率較低，利用熒光粉制備出一種效率較高，被其稱為"蘋果綠"的LED用于手機背光源，取得了較好的經(jīng)濟效益。ED的發(fā)光波長還很難精確控制，因而會造成有些波長的LED得不到應(yīng)用而出現(xiàn)浪費，例如需要制備470nm的LED時，可能制備出來的是從455nm到480nm范圍很寬的LED，發(fā)光波長在兩端的LED只能以較低廉的價格處理掉或者廢棄，而采用熒光粉可以將這些所謂的"廢品"轉(zhuǎn)化成我們所需要的顏色而得到利用。上海熒光粉的視頻</p></p><br
