Pehea e hoʻololi ai ka sima uila i ka pō

I koʻu wā kamaliʻi, hoʻopili koʻu makuahine i mau hōkū ʻālohilohi-i-ka-ʻeleʻele ma luna o koʻu keʻena moe. I kēlā me kēia pō, nānā au me ka mahalo i kaʻu galaxy pilikino kupaianaha. ʻO ka mystique ma hope o ka ʻālohilohi nani i ʻoi aku ka hoihoi. Akā ʻoiai ʻo ka ʻike ʻana i ka physics o ka fluorescence, ʻoi aku ka ikaika o ka phenomena. ʻO nā mea ʻālohilohi e hoʻopuka wale ana i ka ikehu māmā i lawe mua ʻia mai ko lākou puni.

ʻO ka Fluorescence a me ka phosphorescence ʻelua mau huaʻōlelo like ʻole e wehewehe ana i ka hoʻopuka ʻia ʻana o ka mālamalama mai kahi mea, kahi mea i ʻike ʻia he photoluminescence. Ke komo ka malamalama e kekahi mea luminescent kiʻi, e like me ka phosphor, hauʻoli nā electrons a lele i nā mokuʻāina kiʻekiʻe. Hoʻomaka ka fluorescence i ka wā e hoʻomaha koke ai kēlā mau electrons hauʻoli i ko lākou kūlana honua, e hoʻihoʻi i kēlā ikehu māmā i ke kaiapuni.

Loaʻa ka Phosphorescence i ka wā i hoʻomoʻa ʻia ai ka ikehu o nā electrons ʻaʻole wale ka mea e hauʻoli ai nā electron, akā e hoʻololi pū i ke kūlana spin electron. He kauā kēia electron i hoʻololi pālua ʻia i nā lula paʻakikī o ka quantum mechanics a pono e mālama i ka ikehu māmā a hiki i ka loaʻa ʻana o kahi kūlana paʻa e hoʻomaha ai. ʻO kēia ka mea e hiki ai i ka mea ke mālama i ka mālamalama no nā manawa lōʻihi ma mua o ka hoʻomaha. ʻO nā mea ʻālohilohi ka mea maʻamau i ka fluorescent a me ka phosphorescent i ka manawa like, e helu ana i ka hoʻohana like ʻana o nā huaʻōlelo (Boundless 2016). ʻO ka mana o ka mālamalama e hiki ai i ka ikehu lā ke hoʻohua maoli.

Hoʻohana i ka fluorescence a me ka phosphorescence no ko mākou mau alanui

ʻO koʻu manaʻo i nā mea a pau kiʻi-luminescent ua kokoke e māʻona ma mua o koʻu mau manaʻo hihiu loa, ma muli o kahi mea hou a Kauka Jose Carlos Rubio ma ke Kulanui o San Nicolas Hidalgo ma Mexico. Ua hoʻokumu maikaʻi ʻo Kauka Carlos Rubio i ka sima glow-in-the-dark ma hope o ʻeiwa mau makahiki o ka noiʻi a me ka hoʻomohala ʻana. Ke hoʻomau nei kēia ʻenehana patent i ka hana o ka sima akā e hoʻoneʻe i ka microstructure opaque crystalline by-product microstructure, hiki ke ʻike ʻia nā mea phosphorescent (Elderridge 2016). Hoʻopiʻi ka sima i ka piha piha i loko o ʻumi mau minuke o ka ʻike ʻana i ka mālamalama maoli a e ʻā a hiki i 12 mau hola i kēlā me kēia pō. Paʻa loa ka fluorescence o ka mea i ka hoʻāʻo o ka manawa. E ho'ēmi ka'ōlinolino ma ka 1-2% wale nō i kēlā me kēia makahiki a mālama i ka mana o 60% no nā makahiki he 20 (Balogh 2016).
