style="text-indent:25px">硅酸鹽體系主要有M2SiO4:Eu2+和M3SiO5:Eu2+(M=Ca,Sr,Ba)兩種熒光粉，前者可主要是綠粉和黃粉，后者是橙色粉。硅酸鹽熒光粉其可靠性相對(duì)較差，目前采用硅酸鹽主要是其**方案。當(dāng)Sr含量較多時(shí)其波長會(huì)向長波方向移動(dòng)，Ba含量較多時(shí)則會(huì)向短波方向移動(dòng)，其半波寬較YAG要窄，通常黃光附近的視感度高的部分發(fā)光多，有利于高輝度、高流量的光譜。在眾多材質(zhì)的熒光粉中，氮化物是寵兒，目前常見的綠粉、黃粉、橙粉及紅粉甚至青粉都有它的影子。熒光粉的價(jià)格因質(zhì)量不同、種類不同而不同。</p><div

style="text-indent:25px">夜光粉，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，在停止光照射后，在緩慢地以熒光的方式釋放出來，在夜間或者黑暗處，仍能看到發(fā)光，持續(xù)時(shí)間長達(dá)幾小時(shí)至十幾小時(shí)。一、吸光：儲(chǔ)光粉在亮處吸收各種可見光，光線越強(qiáng)越好，光效依次為紫外光、陽光、白熾燈光、黃色燈光；? 二、蓄能：蓄光粉將吸收到的光能儲(chǔ)存到粉體中，通過夜明粉特有的機(jī)能，再將光能釋放出來。但這里要注意，這個(gè)蓄能過程不同于蓄電池，蓄電池的能量是在使用時(shí)才釋放，而夜光體的吸光—蓄能—發(fā)光過程是同時(shí)進(jìn)行的，其中發(fā)光過程滯后并加長，在暗處發(fā)光時(shí)間較高可達(dá)十幾個(gè)小時(shí)；? 三、發(fā)光：起始亮度較高，逐漸衰減直至無光。開始十幾分鐘內(nèi)，亮度衰減較快，之后衰減速度減緩。發(fā)光體有長短效之分（長短指發(fā)光時(shí)間）。上海好用的熒光粉批發(fā)</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2898101.html</p></div></div></div></div></div><div
