style="text-indent:25px">熒光粉，俗稱夜光粉，通常分為光致儲(chǔ)能夜光粉和帶有放射性的夜光粉兩類。光致儲(chǔ)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(chǔ)存起來(lái)，在停止光照射后，再緩慢地以熒光的方式釋放出來(lái)，所以在夜間或者黑暗處，仍能看到發(fā)光，持續(xù)時(shí)間長(zhǎng)達(dá)幾小時(shí)至十幾小時(shí)。人們?cè)谘芯糠烹姲l(fā)光現(xiàn)象的過程中開發(fā)了熒光燈和熒光粉。當(dāng)時(shí)的熒光燈使用硅酸鋅鈹熒光粉，發(fā)光效率低并有毒性。發(fā)明鹵磷酸鈣熒光粉并用在熒光燈內(nèi)，在照明領(lǐng)域引起了一次**。這種粉發(fā)光效率高、無(wú)毒、價(jià)格便宜，一直使用。金華質(zhì)量的紫紅熒光粉</p></p><br
